Lets say I have function f= (x^3+y^3+z^3). For a constant y and z, I want to plot function 'f' between xmin<x<xmax using fplot. Is this possible?

f = @(x,y,z) x^3+y^3+z^3;
ycon = 5;
zcon = .34;
fun = @(x) f(x,ycon,zcon);
xmin = -4;
xmax = 6;
fplot(fun, [xmin, xmax])

Thanks, that works. I have a related question about plotting a function given as an integral depending on a parameter, but that seems to deserve it's own post so I'll start a new discussion.

Never mind. I found it
fplot(@(x) f(x,yvalue,zvalue), [xmin xmax])
