why am I getting this error, Subscript indices must either be real positive integers or logicals, when trying to set axis limits?

I am plotting two volltage against time, I try to set the axis as follows,

axis([-0.1, 0.1 40 140])

but get this error; Subscript indices must either be real positive integers or logicals.

In the Command Window, type:

whos axis

I suspect you have a variable named ‘axis’ that is causing the error. The solution: rename the variable.
