How to convert a row vector into a matrix ???

Using this code : C=reshape(C,[10,10]); I am getting an error like this : Error using reshape To RESHAPE the number of elements must not change.

Error in content (line 48) C=reshape(C,[10,10]); Please help me....

If you use reshape.... C=reshape(C,[10,10]); The matrix C (row vector) must have 10*10 = 100 elements. Does your C have 100 elements? You can convert a array into matrix of order [m,n] provided m*n = numel(C) i.e the m*n should be equal to the number of elements in C.

Eg.

C = rand(100,1) ;
C = reshape(C,[10,10]) ;

Note that you can leave the number of rows or columns blank if you know for example that you want 10 columns but don't want to calculate how many rows that will take:

C = reshape(C, [], 10); %use 10 columns and as many rows as necessary

The number of elements in the matrix still needs to be a multiple of 10 for it to work.
