CALLING SEQUENCE

[coef]=findcoef(str,car)

PARAMETERS

Input

* str = the equation analyzed

* car = the default car for the beginning of the coefficients

 

Output

* coef = the names of the coefficients

DESCRIPTION

In an equation where the coefficients are given by default (car1,...,carn) finds the last coefficient in this equation and infer the names of the coefficients

EXAMPLE

findcoef('a1+a2*x1+(a3-a2)*x2+(a4-a3)*a5b','a')
