I know we can use the A= max(image,[],3) to get the maximum intensity. But I wonder to know how I can calculate the 3D volume by using the maximum intensity projection. And then I can rotate the 3D volume. Thank you.

Hopefully "image" is not the actual name of your image, but you can just use sum:

volume = sum(image(:));

Thank you Image Analyst. But I want to show the volume by using the MIP algorithm. Do you know how to implement?

Scan each pixel column in the image extracting the Z vector and sending it into max().

[rows, columns, numSlices] = size(Img);
outputImage = zeros(rows, columns, class(Img)); % Or whatever class you want.
for col = 1 : columns
    for row = 1 : rows
        thisZVector = Img(row, col, :);
        maxValue = max(thisZVector);
        outputImage(row, col) = maxValue;
    end
end
