MATLAB help!

Long story short, my “programming prep” course threw me into MATLAB so hard I hit the ground and bounced.

Anyway, I need to create a 1200 x 1200 matrix of zeros with the value 75 on the minor diagonal.

Help!

How clean does the code need to be?

“MATLAB”

Did you try turning it off and then turning it back on again?

I really don’t care. As long as it can help me understand arbitrary matrices better.

A = flip(75*eye(1200)); *Edited because I had my test dimension of 5 in here at first

As clean as I can get it in one line.

“eye” creates the identity matrix of ones on the diagonal and zeros everywhere else. multiplying by 75 is self explanatory, and flip flips the rows vertically (1st row becomes last, last is first, etc..)

You shouldn’t be handling minors anyway.

Better them being sober than your drunken minors. You sicken me, crustacean.

MATLAB is a poo.

I can’t help you there my coding is pure shit.

This is as clean as it gets. I spend probably 33% of my life in MATLAB and can’t think of a better way.

Hey I provide safe haven for those drunk children. What charitable act have YOU done lately? Other than save my life that one time.

I told inner-city rapscallions to stay in school and don’t do drugs.

Did you tell them to stay in PUBLIC schools, though? They’re all doomed.

I told them to stay out of God’s Kingdom.

How convenient, someone else currently working in MatLab. High five?

Too angery to high five.

If this is being graded, the instructor is going to know this isn’t his own work. In the beginning it’s for loops or nothing for making matrices!

ah, MATLAB. I have a small program written in it which will generate biquad coefficients in both S- and Z-domain. It’s a nice, small, 6 MB application.

Which needs the 800 MB MATLAB compiler runtime in order to be usable. The only one worse than Mathworks is National Instruments.
