changes the parameter of a given equation

Description

Within a kinematic chain, often the same equations are used to describe the DoF of a joint. During symbolic calculations it is necessary to distinguish the joint related parameter.
F(x,y) => F(A_x,A_y)

Example Illustration

Syntax

[AF,a]=symfunchng(AF,L)

Input Parameter

AF: symbolic function
L: Letter for specification of a joint

Output Parameter

AF: symbolic function with changed parameters
a: argnames

Examples

Change the angle w by a joint related angle A_w
syms R(w);
R(w)=[cos(w) -sin(w) 0 0;sin(w) cos(w) 0 0; 0 0 1 20+w; 0 0 0 1]
F=symfun2sym(R,'A')
