question:As a prompt generator for a generative AI called "Midjourney", you will create image prompts for the AI to visualize. I will give you a concept, and you will provide a detailed prompt for Midjourney AI to generate an image. Please adhere to the structure and formatting below, and follow these guidelines: Do not use the words "description" or ":" in any form. Do not place a comma between [ar] and [v]. Write each prompt in one line without using return. Structure: [1] = 霓虹 [2] = a detailed description of [1] with specific imagery details. [3] = a detailed description of the scene's environment. [4] = a detailed description of the compositions. [5] = a detailed description of the scene's mood, feelings, and atmosphere. [6] = A style (e.g. photography, painting, illustration, sculpture, artwork, paperwork, 3D, etc.) for [1]. [7] = a detailed description of the scene's mood, feelings, and atmosphere. [ar] = Use "--ar 16:9" for horizontal images, "--ar 9:16" for vertical images, or "--ar 1:1" for square images. [v] = Use "--niji" for Japanese art style, or "--v 5" for other styles. Formatting: Follow this prompt structure: "/imagine prompt: [1], [2], [3], [4], [5], [6], [7], [ar] [v]". Your task: Create 4 distinct prompts for each concept [1], varying in details description, environment,compositions,atmosphere, and realization. Write your prompts in english. Do not describe unreal concepts as "real" or "photographic". Include one realistic photographic style prompt with lens type and size. Separate different prompts with two new lines. Example Prompts: /imagine prompt: cute dog, fluffy fur, wagging tail, playful expression, sitting on a grassy field, under a clear blue sky, with a colorful collar, in a natural and vibrant setting, by a lake, captured with a Nikon D750 camera, 50mm lens, shallow depth of field, composition focused on the dog's face, capturing its joyful spirit, in a style reminiscent of William Wegman's iconic dog portraits. --ar 1:1 --v 5.2 /imagine prompt: beautiful women in the coffee shop, elegant and sophisticated, sipping a cup of steaming coffee, natural sunlight streaming through the window, soft and warm color tones, vintage decor with cozy armchairs and wooden tables, a bookshelf filled with classic novels, delicate porcelain teacups, a hint of aromatic coffee beans in the air, captured by a Leica M10 camera, 35mm lens, capturing the essence of timeless beauty, composition focused on the woman's face and hands, reminiscent of a painting by Leonardo da Vinci. --ar 1:1 --v 5.2 /imagine prompt: A captivating Halo Reach landscape with a Spartan amidst a battlefield, fallen enemies around, smoke and fire in the background, emphasizing the Spartan's determination and bravery, detailed environment blending chaos and beauty, Illustration, digital art, --ar 16:9 --v 5
answer:/imagine prompt: neon lights, vibrant colors illuminating the city streets, reflecting off wet pavement, creating a surreal and enchanting glow, surrounded by towering skyscrapers and bustling crowds, a fusion of modern technology and urban energy, captured with a wide-angle lens, emphasizing the expansive cityscape, in a style reminiscent of Shinichi Maruyama's long-exposure night photography. --ar 16:9 --v 5.2 /imagine prompt: a neon-lit alleyway, filled with flickering signs and graffiti, casting an eerie glow on the worn-out walls, showcasing the grit and soul of the urban underbelly, a hidden sanctuary for late-night wanderers, captured with a vintage film camera, using a fisheye lens to distort the surroundings, adding a sense of otherworldliness, in a style reminiscent of Daido Moriyama's raw and poetic street photography. --ar 9:16 --v 5.2 /imagine prompt: a neon paradise, an extravagant nightclub with pulsating lights and electrifying energy, a fusion of futuristic and art deco designs, where people lose themselves in a kaleidoscope of music and dance, captured with a high-speed lens, freezing the dynamic movements of the crowd, in a style reminiscent of Martin Schoeller's hyper-detailed portraiture, highlighting the individuality and passion of the partygoers. --ar 16:9 --v 5.2 /imagine prompt: a neon-lit cyberpunk cityscape, a dystopian metropolis filled with towering holographic advertisements and flying vehicles, immersed in an eternal twilight, blazing neon lights reflecting off rain-soaked streets, capturing the juxtaposition of technological advancement and urban decay, portrayed with a digital illustration style, incorporating intricate details and vibrant colors, reminiscent of Simon Stålenhag's imaginative and haunting artworks. --ar 16:9 --v 5
question:在Matlb中，A代表矩阵1，B代表矩阵2，A的逆乘以B用代码怎么表示
answer:在Matlab中，可以使用`inv()`函数来求矩阵的逆，使用`*`符号来表示乘法运算。所以，A的逆乘以B可以用以下代码表示： ```matlab A_inv_times_B = inv(A) * B; ``` 其中，`A_inv_times_B`是结果矩阵。请确保矩阵A是可逆的（即非奇异矩阵），否则可能无法计算逆矩阵。
question:那-A/B是什么意思
answer:在Matlab中，`/`符号表示矩阵的右除法运算，即求解方程`A * X = B`，其中A为系数矩阵，B为等号右边的矩阵，而X为未知矩阵。当我们将方程左边的A乘以-1时，我们可以得到方程`-A * X = B`，即`A`的相反数除以`B`，这在Matlab中可以表示为`-A/B`。 因此，`-A/B`表示求解方程`-A * X = B`，其中`A`是系数矩阵，`B`是等号右边的矩阵。
question:汽车控制的一阶惯性系统如何线性化
answer:汽车控制的一阶惯性系统可以由汽车的加速度与输入（例如油门开度）之间的关系来描述。线性化是将非线性系统在某个操作点附近近似为线性系统的过程。在汽车的一阶惯性系统中，可以通过使用泰勒级数展开来进行线性化。具体步骤如下： 1. 选择一个操作点，用于线性化。这个操作点通常是汽车的平衡状态，即零输入的状态。 2. 根据操作点的数值，计算非线性系统的初始条件。这些初始条件包括汽车的速度、加速度和输入。 3. 确定线性化的输入变量。在汽车的一阶惯性系统中，通常选择油门开度作为输入变量。 4. 将非线性系统表示为状态空间形式，其中状态可以是汽车的速度和加速度。 5. 对非线性系统的状态空间方程进行泰勒级数展开。保留一阶项，并忽略高阶项。 6. 对展开后的方程进行线性化。 7. 将输入变量写为零，以得到线性系统的状态空间方程。 线性化后的系统可以用来设计控制器、进行系统分析和性能优化等。请注意，线性化结果只在操作点附近是有效的，系统的动态行为在远离该点时可能会产生误差。因此，在进行线性化时需要谨慎选择操作点。
