Thread: Excel to matlab

Hello,

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?
thx

More information needed, looks like some of the data in the matrix is not numeric.

yes, there were one field empty, so that is why it showed me all Nan for all of the matrix.

Thx
