How do I call this function into my main code and assign an output to it ?

Please can anyone clarify me on this. I have a function file named “decompose_kernel” and I have another .m file containing my codes with coefficients/outputs (CA, CH, CV, CD). These outputs are approximation and detail coefficients I extracted from my input image. I do wish to apply separable filter algorithm contained in the function file named “decompose_kernel” on these coefficients (CA,CH,CV,CD).

How do I call this function “decompose_kernel" into my main code and assign an output to it ?

I will appreciate your suggestions. Thanks

If I got this correct, you got 2 files:

%mainfile.m

... some code and variables CA, CH, CV, CD

and

%decompose_kernel.m

function [outputarguments] = decompose_kernel(inputarguments)

... some code

end

If this is correct, I assume you never really worked with functions much before and should read up on how to use them ( https://mathworks.com/help/matlab/ref/function.html ).

So if you want to use the function decompose_kernel in your main file and use the variables CA/CH/CV/CD, you can do it like this:

%mainfile.m

... some code and variables CA, CH, CV, CD
[output] = decompose_kernel(CA, CH, CV, CD);
