How can I get the max of the values of an array with Numeric Type "double"?

I have an array that is filled with numbers like

a = [0.007 0.008 0.009]

In the workspace the value of a is 1x68 double.

I tried

max(a) : "Subscript indices must either be real positive integers or logicals."

or

realmax(a) / flintmax(a): "Input must be 'single' or 'double'"

So how can I get the maximum value? I want 0.009 as answer.

Thanks in advanced!

max(a) should work unless you have accidentally overwritten max by using it as a variable name. In that case it would try to use a as an index into your array called max.

Thank you!

Whatever I did before...I restarted Matlab and it worked with max(a)!
