That is prod sz must be the same as numel a.
Convert vector to matrix matlab.
Matlab contains a built in function to reshape matrices that you can use to turn any matrix into a single row a vector.
If dim is 1 or 2 then each cell contains a column or row vector respectively.
Beyond the second dimension the output b does not reflect trailing dimensions with a size of 1 for example reshape a 3 2 1 1 produces a 3.
If dim is not specified then c is the same size as a.
For example to convert 1 2.
Each element of sz indicates the size of the corresponding dimension in b you must specify sz so that the number of elements in a and b are the same.
The function creates the matrix one row at a time filling the rows with elements from vec in order.
The program is especially useful in the field of linear algebra which involves vectors and matrices.
How can i do this.
A vector is simply a list of numbers.

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.
Convert vector to matrix.
If dim 2 then each cell contains an array whose dimth dimensional length is size a dim and whose other dimensions are all singletons.
Mat vec2mat vec matcol converts vector vec to matrix mat with matcol columns.
The str2num function does not convert cell arrays or nonscalar string arrays and is sensitive to spacing around and operators.
A matrix is similar but contains multiple rows and columns of numbers.
So taking the kronecker product of a row of 1 s and a column vector effectively copies that column vector into every cell of the textbf 1 n t.
Output size specified as a row vector of integers.
X str2num chr converts a character array or string scalar to a numeric matrix.
The input can include spaces commas and semicolons to indicate separate elements.
If str2num cannot parse the input as numeric values then it returns an empty matrix.
If dim is a scalar then c contains numel a size a dim cells.
