im new to matlab, so i would like somebody to help me to solve one problem.
I have made matrixs in excel, using xlsread funcion i bring tehm to matlab.
when i ask matlab to show me the matrix it shows me with no probelm. but when i need to do some operations with them f.e. B=A*K*A' it calculates and shows the matrix B filled with "NaN" what should i do to see the numbers??? i know that numbers are real, because i've tried it with Mathcad and i got normal numbers?
does anybody knows what is wrong?
