Matrix Operations

This section tests basic numerical skills in MATLAB, which are required for all applications. Required: Where questions ask you to use a specific matrix then reference your previous definitions of it (do not keep typing in numbers).

1.1

Let rm

[11 12 13]

14 15 16

17 18 19

20 21 22

Required: Do not type all the numbers in- use one or more colons (":") to generate the numbers somehow.

1.2

Let rmsqr = the element-by-element square root of rm.

1.3

Let rm2- the square of the matrix defined by the first three rows of am. Hint: Always use proper matrix algebra unless element-by-element operations are mentioned explicitly.

1.4

Let rmtrans2 - the matrix rm multiplied by the transpose of rm.

1.5

Let xmslice = the first two rows of arm joined alongside with the transpose of a matrix made from columns two and three of rm. Hint: The result is a 2 by 7 matrix.
