For MATLAB

The last thing one discovers in composing a work is what to put first. -Blaise Pascal "Pascal's triangle is formed by rows of numbers. The first row has entry 1. Each succeeding row is formed by adding adjacent entries of the previous row, substituting a 0 where there is no adjacent entry."1 A Pascal matrix is formed similarly. The symmetric 4 times 4 Pascal matrix that corresponds to the outlined portion of the graphic above is shown below. [1 1 1 1 1 2 3 4 1 3 6 10 1 4 10 20] Write a function called PascalMat that takes an integer input n and returns a n times n symmetric Pascal matrix as an output variable You may not use the MATLAB function pascal in your function, but you may use it to compare outputs
