I don't know how to enter the code for this question in MATLAB, can someone please give me some guidance on how to answer it? Image has been attached
this is what I have so far: a=[1 3; 2 -4; -2 6], b=[0 1; -1 3; 2 6], c=[1 4; 5 6], d=[2 -3 0; 5 6 -4] ##### 1 CommentShowHide None

This is a pretty basic question. My recommendation would be to watch this MATLAB Onramp tutorial, to learn the fundamentals.

Hi John,
You can do like this, but first I will suggest you to watch basic MATLAB from here MATLAB Onramp - MATLAB & Simulink Tutorial (mathworks.com).
a=[1 3; 2 -4; -2 6];
b=[0 1; -1 3; 2 6];
c=[1 4; 5 6];
d=[2 -3 0; 5 6 -4];
%here .^ is for elemetary square of a matrix
matrix = a - 2*b*(c.^2) + 3*d';
Hope this helps!
