Im getting an error in Matlab command window saying ' Matrix dimensions must agree' for x1=x.*w. Could sum1 say me wats wrong here??

Probabaly dimensions of your inputs x & w are not compatible.

Use below command for checking dimensions of x & w:

whos x w

Have a look here at the answer, or any other previous answered questions regarding 'index exceeds matrix dimensions' problems around this forum.

You are trying to access a value in your matrix that does not exists.

You should do an array instead with no for loop and no separate variables:

e = -5 + linspace(-5, -8, 7);

but I don't know what PP is.
