在MATLAB中动态改变变量名。

This script is being used for image processing by multiplying a set of 2000 images with a mask and then summing the values in each frame. These values are entered into a row vector called Intensity.

该脚本被用于图像处理，通过将一组2000个图像与一个掩码相乘，然后将每个帧中的值相加。这些值被输入到一个称为强度的行向量中。

I am trying to end up with 20 row vectors called intensity1, intesity2...intensity20, is there a straight forward way to change the name of the Intensity row vector upon every loop iteration?

我尝试用20个行向量，称为强度1,intesity2…强度，在每个循环迭代中是否有一个直接的方法来改变强度行向量的名称?

for m=1:20   

 mask=bigrating(m,m,0);

        for n=1:2000  
            I=sum(sum(imread((sprintf('image%05d.tif',n))).*(mask)));
            Intensity(n)=I;
        end

save('filepath','Intensity')

end

Because you wanted dynamically named intensity1, intensity2,....intensity20 etc, the following should work for you:

因为你想要动态命名的强度1，强度2，强度20等，下面应该为你工作:

for m = 1:20
    mask = bigrating(m,m,0)
    for n = 1:2000
        I=sum(sum(imread((sprintf('image%05d.tif',n))).*(mask)));
        eval(['intensity' num2str(m) ' = I'])
    end
    save('filepath', ['intensity' num2str(m)])
end
