% Sample Code
max_index = find(sample.data1 == values,1,'first');
% max_index is always above 100 based on the nature of the data
X = sample.data1(max_index - 100: max_index + 100);
Y = sample.data2(max_index - 100: max_index + 100);
I was trying to generate code based on MATLAB coder, however I am stuck with the error: 'Expected a scalar value. This expression has size [:? x 1].'
I understand that max_index could be empty or (max_index - 100) could be empty, hence this error. How to properly declare those variables to avoid this error?
Max_index is scalar value and cannot be below 100 based on the nature of used data (also used If loops to avoid such condition).

Try this:
% Sample Code
tol = 10^-3 ; % can be changed
idx = find(abs(sample.data1-values)<tol) ;
max_index = idx(1) ;
