See scale_load() 
<http://www.pserc.cornell.edu/matpower/docs/ref/matpower6.0/scale_load.html> 
for changes in load or apply_changes() 
<http://www.pserc.cornell.edu/matpower/docs/ref/matpower6.0/apply_changes.html> 
for a generic mechanism for applying changes to an existing case. You can also, 
simply load the case into a struct using loadcase() and then modify parameters 
directly. For example, to double the reactance of branch 3 …

define_constants;
mpc = loadcase('mycase');
mpc.branch(3, BR_X)  = mpc.branch(3, BR_X) * 2;

Hope this helps,
