Question

I don’t know why I have this strange error when using Octave on Windows 7 64 bit :

when I use ones(100:100) to declare a matrix 100×100. No problem. But when I use : ones(10:100) I will have error :

memory exhausted or requested size too large

And if I use ones(10:15) I must wait for long time (about 30 seconds) to have answer.

Please explain for me this error.

Thanks 🙂

Answer 1

Your syntax is wrong. To create an m x n matrix it should be:

ones(m,n)

e.g.

ones(100,100)

or

ones(10,15)
