Help with the interpolate function

I have a vector of x-coordinates a=[64x1] and a vector of y coordinates b=[64x1]. I want to use interpolate to find the values at different points along the x-axis, which is vector c=[10x1], if that makes sense.

Right now im doing interp(a,b,c) and I get back an error that says.

Operands to the and && operators must be convertible to logical scalar values.

Error in interp (line 56) if l < 1 r < 1 cutoff <= 0 cutoff > 1

I looked at the user guide but it doesn't seem to make any sense.

Use interp1 instead of interp

Cool thanks

The function you want is interp1 (with "1" in the end).
