你生成错了，是Randon变换并不是Random变换

非常抱歉，我的理解有误。你是想了解如何编写一个在MATLAB中实现随机变换（如随机裁剪、缩放、旋转等）的函数对图像进行操作，对吗？下面是相关的代码示例：

function transformed = randomTransform(image, scaleRange, rotationRange, translationRange)
    % 检查输入
    if ~isnumeric(image) || ~(isfloat(image) && all(image(:) >= 0))
        error('Input image must be a numeric matrix with non-negative values.');
    end

    % 获取图像尺寸
    [height, width] = size(image);

    % 随机缩放
    scale = scaleRange(1) + (scaleRange(2) - scaleRange(1)) * rand();
    newHeight = round(height * scale);
    newWidth = round(width * scale);
    cropSize = min([newHeight, newWidth]);
    topCrop = floor((height - cropSize) / 2);
    leftCrop = floor((width - cropSize) / 2);
    croppedImage = image(topCrop+1 : topCrop+cropSize, leftCrop+1 : leftCrop+cropSize, :);

    % 随机旋转
    rotation = rotationRange(1) + (rotationRange(2) - rotationRange(1)) * rand();
    rotationMatrix = imrotate(croppedImage, rotation, 'bilinear');

    % 随机平移
    translationX = translationRange(1) + (translationRange(2) - translationRange(1)) * rand();
    translationY = translationRange(1) + (translationRange(2) - translationRange(1)) * rand();
    translatedImage = imtranslate(rotationMatrix, [translationX, translationY]);

    % 将图像调整回原尺寸
    transformed = padarray(translatedImage, [topCrop, bottomCrop, leftCrop, rightCrop], 0, 'both');

end

% 示例使用
imageToTransform = imread('your_image_path.jpg'); % 替换为你的图片路径
transformedImage = randomTransform(imageToTransform, [0.8, 1.2], [-15, 15], [-5, 5]);
imshow(transformedImage);

这个函数首先检查输入是否为数值图像，然后随机裁剪、旋转和平移图像。记得替换 `imread('your_image_path.jpg')` 为实际的图片路径。
