The extrinsic function 'toc' is not available for standalone code generation. It must be eliminated for stand-alone code to be generated. It could not be eliminated because its outputs appear to influence the calling function. Fix this error by not using 'toc' or by ensuring that its outputs are unused.
Find below code
function y = fcn
%#codegen
persistent temp;
coder.extrinsic('tic')
if isempty(temp)
tic;
temp = 0;
end
coder.extrinsic('toc')
temp = toc;
y = temp;

The Code generation capabilities for Tic/Toc were added in R2019a. So you can use tic and toc without 'coder.extrinsic' in latest version of the MATLAB and that will resolve the code generation error.

function y = fcn %#codegen
persistent temp;
if isempty(temp)
tic;
temp = 0;
end
temp = toc;
y = temp;
