You have an exam next week and still do not know how to write a for loop in Matlab and how to use the documentation to find out how to do this?

doc for

Matlab does not use curly braces for code branches. This was C. Simply omit them.

The rest of the code is almost working. You do not want to compare the elements with a(1,1), but with b in

if a(i,j) <= a(1,1)

"How often did you get the $5 offer?"

For me, twice in 7 years. One of those two was after I had already done the work, and the person didn't even send the money... The other was $5 to do a homework assignment.

In my experience, as soon as I mention money, the person decides their task is not so urgent after all. I don't recall that I have ever gotten as far as mentioning how much I charge: people lose interest upon finding out that I do charge for writing custom programs or for private consultation.

The offer of payments in the funny magnitude of some US$ came about twice per month. Assisting naive students with cheating might be more lucrative if you are willing to blackmail and ask for more money after the exams.

This forum offers assistance for free and I'm sure you can get all homework question solved here, if the own effort is shown and specific questions are asked.

Some years ago a person offered 5$ per minute, seriously, for a work over some month. He was a hedge fond manager, expected a 25/8 support and needed a software to destroy companies such, that the most money can be squeezed out. Frightening. I thought about how I would look, if he buys the company I'm employed in and crush it. Career switches are overestimated.
