I had a similar question to this eariler in which you were told to take inputs z and x from a function and create a matrix of dimension x or z, whichever is larger.
i was told to do something like this:
x = -100:100;
z = -100:100;
myMatrix = randi(100, max(x,z));
do i do the same here but replace the max with min?
thanks for the help.

Gurinder - no, this question is different from the previous one. It is asking you to create a function whose input is a matrix (of any dimension) and the function then finds (and presumably returns) the smalles value in the matrix. So if the matrix were
[6 2 3;
4 5 1]
then your function (when passed this matrix) would return 1 since that is the smallest value in the matrix.

Hint: First reshape the input x array into a 1D vector and work with that inside your function.
