hi, I made a code like below:
clc
syms xx t
xx=0:0.01:1;
yy=zeros; yyy=zeros;
for i=1:101
yy(i)=int(((1+2*t)/(1-t))^2,0,xx(i));
yyy(i)=xx(i)*((1+2*xx(i))/(1-xx(i)))^2/yy(i);
end
loglog(1-xx,yyy,':');
And I definitely have the Symbolic Math Toolbox. when I type ver in the prompt I can see it.
But why does this code make an error to me? My friend said he had no problem with this; and why do I?
Below is my ver result, FYI

you need to rename C:\Users\iks11\OneDrive\문서\MATLAB\syms.m or remove it from your search path.

The function you've written or downloaded named syms.m in your OneDrive is shadowing the syms function that is part of Symbolic Math Toolbox, preventing MATLAB from calling the Symbolic Math Toolbox function.
Rename your syms.m function to a different name, maybe something like mysyms.m.
