Please compile the function file function a=test(b) to satisfy when the output matrix a is the transpose of the input matrix b. Please use a for loop instead of the built-in transpose function of matlab; Please directly use the source code of the f

A = [1 2 3;4 5 6] B = MyTranspose(A) Looks okay to me.
