Vector To Matrix MatlabMATLAB contains a built-in function to reshape matrices that you can use to turn any matrix into a single row -- a vector. Therefore, just using reshape by itself will place the elements in the columns. Reshape Vector into Matrix Reshape a 1-by-10 vector into a 5-by-2 matrix. The program is especially useful in the field of Linear Algebra, which involves vectors and matrices. This is not conversion but you are adding new elements to the original vector : If you have a vector of size Mx1 you can convert it to matrix using function reshape to get a matrix of size PxN such M=P*N. For example, Theme Copy Vector = [1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16] and I want Theme Copy.

I want put r in row 1 of report matrix. To create a column vector c of n plus m elements, by appending these vectors, you write − c = [c1; c2] You can also create a matrix c by appending these two vectors; the vector c2 will be the second column of the matrix − c = [c1, c2] However, to do this, both the vectors should have same number of elements. If they are column vectors: [A, B, C] or [A, B, C].
