Diff function: How to calculate the difference of two values

Hey,

for a bigger task i need to use the diff function.

When I type in:

diff(12.22, 13.22) it should me give a 1 back, instead i get an error. Why?

thanks for comments

Syntax error. See the doc page. You are asking it to take the diff of 12.22 13.22 times. All the values you want to take the difference of need to be in the first input. Try this.

diff([12.22,13.22])

ans = 1

Exact.

The first step in case of an error is do ask help or doc to explain the syntax of the command:

help diff
% If this is not exhaustive enough:
doc diff
