I am converting some of my code to C/C++ and I am getting as expected a lot of error. For example the following piece of code returns error while building due to the fact that i am using a cell, something that is not supported by the compiler. What can i do? Thank you in advance for your time and consideration

K = logical(diff([x(1)+abs(x(1))*2e-7; x; x(end)-abs(x(end))*2e-7])<=0); % 
L = {K(2:end) & [K(2); K(2:end-1)~=K(3:end)]}; 
L = cell2mat(L(1));

In this particular case, the cell array use is not absolutely necessary. Try

K = logical(diff([x(1)+abs(x(1))*2e-7; x; x(end)-abs(x(end))*2e-7])<=0);
L = K(2:end) & [K(2); K(2:end-1)~=K(3:end)];

A cell array can often be replaced with a matrix when all cells of the cell array are of the same type. In this particular case, the cell array has only a single element, and therefore all elements are of the same type.
