Grocer Function
NAME
findcoef - find coefficients in an equation
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')
This example gives ['a1';'a2';'a3';'a4']. The main usage is in econometric functions where the user must give the text of an equation (nls, twosls, threesls,...).
