Hello All, I am converting matlab script to C++.
Here is a test function which is similar to my project. When i try to generate C code using Matlab coder it is throwing index exceeds its valid range. What is the meaning of this error. Could anyone guide me how to fix this, please.
function [a]=test()
% a=repmat(struct('in1',zeros(1,5),'in2',ones(1,5)),1,5);
years = 1950:10:1990;
service = 10:10:30;
wage = [150.697 199.592 187.625
179.323 195.072 250.287
203.212 179.092 322.767
226.505 153.706 426.730
249.633 120.281 598.243];
for i = 1:5
a(i).in1=interp2(service,years,wage,15,1975);
a(i).in2=interp2(service,years,wage,15,1970);
end

What happes if you pre-allocate the struct array a? You show some outcommented code already. Or:
a = struct('in1', cell(1,5), 'in2', cell(1,5));

Yes, it is showing size mismatch error. I will post it here. For this error we have to say something like
coder.varsize('a.in1')
coder.varsize('a.in2')
yes, Now it is working fine.
May I ask you why you have used cell instead of zeros or ones.
