how to assign different names for matrices in a for loop..

for ex

if x=[1 2]

if i want I1=[1 1]
I2= [1 2]

for i=1:2
[what must be here??]=[1 x(i)];
end;

since i cant write Ii or I(i) m confused how to assign names in a for loop..

thank u..

use a(i,:) to fill in the whole row with a vector and a(:,i) to fill a
column...

ex: a(1,:) = [1,2]; a(2,:) = [2,2];
if not, a(:,1) = [1;2]; a(:,2)= [2;2];

notice the ',' and ';' separators between row and column assignment
operations.
best, arun.

you are absolutely NOT allowed to do this in ML...

You left out the drunken gremlins which come by night.
They will be named gremlin_1, gremlin_2, gremlin_3, ...
