在 MATLAB Online 中打开

Near the top of the code, you need to add

ac = zeros(4,1);
an = zeros(4,1);
A1 = zeros(size(L));

i still got these errors for the similar code

Walter Roberson 2021-1-23

The first two errors tell me that your input signal I is a 2D array rather than a 3D array (RGB)

A number of the following errors are consequences of that error in size of the input signal.

Like Walter suggested you need to fully difine variables size before accessing it.

You can use %#codegen pragma at the beginning of your function to get all such issues highlighted.

I could modify the function a bit and and get it working with codegen. Please do a diff with the modified code and your code to check what exactly is changed. You can tweek it a little bit to suite your application.

Please use the attached files.

Hope this will be helpful
