Hi everybody, I try to generate C++ Code from my function but I cant use the resample function (it always ends with err "coder.const could not reduce this expression to a constant: Time out exceeded.") although I declare each input as a constant and i have licensed the USP System Toolbox ( license checkout signal_blocks == true). Also I ran the same code with the Matlab 2016b Coder and generated my C++ Code without any problem. So where is the difference? Best regards
My code looks like this:
Q=1000000;
% P=floor(Resampling_Faktor*Q); % floor: rounds to the nearest integer
P = 500000; % for testing
Input=1:0.1:20; % for testing
Input = resample(Input,P,Q,5,20);

Hello Daniel,
Try to increase Constant Folding Timeout value.This can be done in two ways:
1. At the command line, create a configuration object for code generation. Set the property ConstantFoldingTimeout to the value that you want, like 400000:
c = coder.confi;
c.ConstantFoldingTimeout = 4e5;
2. In the Project Settings dialog box, on the All Settings tab, set the field Constant folding timeout to the value that you want.
Regards,
Krishna Madala
