Can anyone show me how to code this algorithm without loops?
It's got me stumped.

Data types are:

degree is an integer
i = degree + 1
j = degree + 1
kx = fltarr( i, j ) ; contains polynomial coefficients
ky = fltarr( i, j ) ; contains polynomial coefficients
x0, y0, xi, yi are float variables or vectors

Here is the code:

xi = 0.0
yi = 0.0
for i = 0, degree do begin
for j = 0, degree do begin
xi = xi + kx( i, j ) * x0 ^ j * y0 ^ i
yi = yi + ky( i, j ) * x0 ^ j * y0 ^ i
endfor
endfor

Many thanks,
Liam.
