Please can somebody help on this

I came across a function i intended to use, and it started by creating arrays of ones like this

 zn = ones(n,1)*10^100.

Please can somebody tell me the meaning and the benefits. thanks

There are many possible reasons, but we can't tell you which one is the best explanation, unless you actually show us that function. You can upload code using the paperclip button, and then pressing both the Choose file and Attach file buttons.

Tijjani - all that line of code

 zn = ones(n,1)*10^100;

is doing is creating an nx1 array of ones and multiplying each element by 10^100. Try doing the above and go through different values of n to see the above work. Perhaps the author of the code is just assigning some max value to all elements in this array.

But, like Stephen said, we cannot tell why the author may want to do this without seeing the code.
