## Matrix within a Matrix  7-Bedrock

## Matrix within a Matrix

Hello everyone,

I have the following matrices:

x = (15 -17)    y = (-6 20)   z = (55 -75)

I would like to combine them to form a new matrix such as,

A = (x y z)

I'm thinking (not sure if its right) A would turn up to be a 1x6 matrix.

A = (15 -17 -6 20 55 -75)

Then I would like to get the maximum absolute value of A which if everything is possible up to this point then the result would be 75.

Any suggestions?

Thanks!

Use

A:=augment (x,y,z).

Then the Minimum of your matrix A will be found with:

MinA:=min (A) = -75

To find the Maximum absolute value use:
MaxAbsA:=max (abs (A))= 75

Some more: Success!

Yes, Your solution is correct. This is the simple way to get the solution of this problem. Same solution also in my mind but you already did good effort.
