I have the following function I do not know why it is not working. Would you please help me?
function [L_e]=L_element(e,nnpe,nn)
% Gather matrix
L_e=zeros(nnpe,nn);
for i=1,nnpe
for j=1,nn
if j==(nnpe-1)*(e-1)+i
L_e(i,j)=1;
end
end
end
end

The mlint is giving you a hint: it wants you to put a semicolon to suppres output. Why would you have an output with the for loop? Because you put a comma instead of a colon:
function [L_e]=L_element(e,nnpe,nn)
% Gather matrix
L_e=zeros(nnpe,nn);
for i=1:nnpe
for j=1:nn
if j==(nnpe-1)*(e-1)+i
L_e(i,j)=1;
end
end
end
end
Of course you can also avoid the nested loop:
function [L_e]=L_element(e,nnpe,nn)
[I,J]=ndgrid(1:nnpe,1:nn);
L_e= J==(nnpe-1)*(e-1)+I ;
L_e=double(L_e);
end
