I have a matrix that it is 321*531. It includes NaN values, which i have to eliminate them. Thus, I used this code:
m=~isnan(x);
v=x(m)';
then it turned to 1*75638. I wanna reshape it to 321*531,but I don't know how can I do this.I have tried reshape function,but it doesn't work.
please help me. thanks

Well, if there are NaN's and you eliminate them, your matrix can not keep its same shape unless you replace them with something else. What's it gonna be?

@navid zed: the number of elements that you have 75638 is not divisible by the number of rows that you want 321:
>> 75638/321
ans = 235.63
What do you imagine happening, should MATLAB magically invent some data to fill in the gap?

If you are okay with replacing NaN values with Zeros then:
A(isnan(A))=0
Here A will be your matrix.
