Hi, Thanks to everyone who replied. Most of these approaches worked. However, i needed to make contours of the defined function. And for this, i needed to define it in a certain way to get the contours. For instance, f[theta_,phi_]:=, f[theta,phi]=, wouldn't work. Right now, i have defined f as f=If[(0<=th<=th0)&&(0<=phi<=phi0),f1,f2]. I still get a long list of errors but i also get the correct contours. Thanks again, Ranga Kidambi On Fri, 5 Feb 1999, Rangachari Kidambi wrote: > > Hi, > > I need to define a function f(theta,phi) as > > f(theta,phi) = f1 if 0 <= theta <= theta0, 0 <= phi <= phi0 f(theta,phi) > = f2 otherwise > > where theta, phi are spherical polar coordinates, <= is less than or > equal to and theta0 and phi0 are constants. > > I have tried using Do loops and If statements but haven't been > successful. > > Thanks for any help > Ranga Kidambi > > >
