Hi guys,
I really need your help with the summation of matrices in Matlab.
I have two matrices (180,360), which counts a total of 129 600 values, with different numbers. I would like to sum all the elements within this two matrices as follows:
• value from the 1st row and 1st coloumn of the 1st matrix sum with the value from the 1st row and 1st coloumn of the 2nd matrix,
• value from the 1st row and 2nd coloumn of the 1st matrix sum with the value of from the 1st row and 2nd coloum of the 2nd matrix,
• and so on until the end.
I tried to do next:
Z = A + B and I get only one value in the last row and last coloumn. All the others values are zero (0) even the values in the both matrices are NOT zero (0). I also tried to use funtion SUM like Z = sum (A + B) but I got the result equel to 2 x Z in the last row and last coloumn.
Is there any other (easy) trick to sum this matrices?

OK, I find out what was wrong in my calculation.
I had (j,i) in the brackets after Izb_hv_bl and Izb_hv_p. Now I deleted this brackets and everything seems to sum right.
I will check that one more time but I thing it will work fine.
Best regards mate.
