COSINES Function

Standard Library basis function that can be used by the SVDFIT function.

result = COSINES(x, m)

x A vector of data values with n elements.

m The number of terms in the basis function.

result An n-by-m array, such that:

result(i, j) = COS(j * x(i))

None.

COSINES consists simply of the following two lines:

FUNCTION COSINES, x, m
RETURN, COS(x # FINDGEN(m))
