Hi,

   I want to multiply 2 matrices one is nx1 and another is nxn ...i know very well that nx1 has to be transposed to be multiplied with nxn...
Can anyone help me in this transpose coding in C language ....
I need it very urgent ....

Thanks in advance

it depends on the structure you're using for your matrix.

hi,

if the matric u wanted to transpose is nx1, then why u r writing a separate logic for transposing and then for multiplying.

Anyway you need to walk through elements one by one. Instead of vertical traverse, you need to horizontal traversal if you transpose.

Got it? if u have the multiplication logic, do the vertical traversal and multiply. thatz it.

nx1 with nxn!,you can't multiply them,if you meant nxn with nx1 your result would be a nx1 matrix.

hi,
yse i know it cannot be multiplied thats why i asked how to transpose a nx1 matrix to 1xn matrix ...as u said ic an multiply nxn with nx1 but i need to multiply nx1 with nxn aso i need transpose ...
as every one know axb is not equal to bxa in case of matrix

okay so tell I am going to multiply 1xn with nxn,i.e for multiplying 1xn with nxn,

             |1 2 3|
|3 2 1| x |0 1 0| = 3 times the first row+2 times the second row +1 time the third row=
             |2 0 0|

                    |3 6 9|+|0 2 0|+|2 0 0|=|5 8 9|

and all of that depends on the structure you are using for your matrix.
