If you specify both N and the spacing then you've overconstrained your
problem. The MATLAB syntax you gave spacing the spacing but not N.
This MATLAB function call specifies N but not the spacing:

Data = linspace(a, b, N);

If you really want to specify both N and the spacing then the last
element of Data might not be exactly b.

Say which one you want and then the IDL folks here can tell you how to
do it.
