X=zeros (1,1301);
time =0:0.05:65;
k=0.05;
for i=2:1301
    X(i) = ((k*(0.293*X(i-1)^2)-(0.542*X(i-1))+0.354)*0.05) +X(i-1);
end
    plot (time, X)
    hold on
    plot (timeopc25, alphaopc25,'--')
 legend('Predicted Data','Experimental data');

It tells, not formed from a valid matlab identifier. What does this mean? Thanx in advance

We don’t have ‘timeopc25’, and ‘alphaopc25’ so we can’t help you with them.

@Star Strider Please check my code and the graph just doesn't converge on the original graph. I have included the timeopc25 and alphaopc25 files too.

This error usually occur when there is a space in an M-file, or other forbidden characters. Check that the script file containing the code has a correct name with no white spaces.

This is incorrect: "my file.m"

This is correct: "myfile.m"
