Basic Matrix Operations

Prob 1

Initialize appropriately a 2x3 matrix A and a 3x1 array x on the command window as follows, and calculate A * x and substitute the calculation result to vector y and display all elements of A.

Initialize a regular matrix appropriately, and make its transpose and inverse matrices.

In addition, make the following three matrices on command window:

• an mxm diagonal matrix whose diagonal elements are all one using function eye().
• an mxn matrix whose elements are all one using function ones().
• an mxn matrix whose elements are all zero using zeros().
