Change part(s) of form


f = fnchg(f,part,value)


f = fnchg(f,part,value) returns the given function description f but with the specified part changed to the specified value.

The character vector or string scalar part can be (the beginning character(s) of) :


The dimension of the function's target


The basic interval of that form

The specified value for part is not checked for consistency with the rest of the description in f in case the character vector or string scalar part terminates with the letter z.


fndir(f,directions) returns a vector-valued function even when the function described by f is ND-valued. You can correct this by using fnchg as follows:

fdir = fnchg( fndir(f,directions),...
           'dim',[fnbrk(f,'dim'),size(directions,2)] );
