HDL Coder errors don't make sense

I get the following HDL coder errors when I try to convert the attached be_alam.m. I have attached the function and the test bench. Please help.

Errors:

be_alam_fixpt:48 Error Found unsupported dynamic matrix type at output port: 0, name 'o1r', in the file/function be_alam_fixpt.

be_alam_fixpt:0 Error MATLAB HDL Coder failed in the code generation phase. See HDL Coder conformance report.

I believe your problem is your call to 'find' around like 50 of be_alam.m. 'find' returns a variable size vector as its result. This will be the proximate cause of the "dynamic matrix type". HDL Coder needs all variables to have a fixed size at all times.

I think you will have to implement the 'find' functionality explicitly, returning a single value.

    min_dis = min(dis);
    for ii = 1:numel(dis)
        if dis(ii) == min_dis
            n = ii;
        end
    end
