changeq

change an equation in a model

CALLING SEQUENCE

model2=changeq(model,indeq,neweq)

PARAMETERS

Input

* model = a model typed list

* indeq =

   - a string vector, the names of the equations to replace

   - or a vector of integers, the indexes of the equations to replace

* neweq = a string vector, the text of the new equations

Output

* model2 = the new model, with the new equations

DESCRIPTION

Changes equations in a model.

EXAMPLE

global GROCERDIR;
// load the model small:
load(GROCERDIR+'\data\small.dat')
// remove the error correction term from equation 'td_p3m_d1':
small2=changeq(small,'td_p3m_d1','delts(log(td_p3m_d1)) = '+...
