What type of built-in functions (such as function Toeplitz) that come with Matlab help us to construct a symmetric matrix (not random) ?

Several of the matrices you can create using the gallery function are symmetric, and some have other interesting and/or useful properties.

If no specific properties needed, then you could use
n = the desired size
M = rand(n);
M = M + M';

Thank you so much. I just want to learn more about the built - in function that can we use to create symmetric function.

squareform() can convert a vector of values representing the upper triangle, into a full symmetric matrix.
