i have 'x' vector which is N*1 column vector
i want to multiply it with its transpose.
(i.e) x' * x
how can i do it
explainme with the code

thanks in advance
 

U can get the inverse of one matrix by a basic mathematical formula. U can refer that formula in basic mathematics books.


inverse(M)= (1/adj(M))* .....

I don't know the correct formula.

Then by ordinary matrix multiplication u can get the result.
Best wishes!

I hav attached one word document. It will be helpful for u.
 

hai preetha,

i need to calculate transpose matrix multication.
not inverse matrix
 

What is actual problem ?
You are already multiplying the vectors in your code.
Are you asking for the steps ?

a = 1:5;
a = a';

b = a' * a;

Are you looking for "b" ?
