The program is especially useful in the field of linear algebra which involves vectors and matrices.
Convert vector to matrix matlab.
The function creates the matrix one row at a time filling the rows with elements from vec in order.
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.
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.
Output size specified as a row vector of integers.

That is prod sz must be the same as numel a.
For example to convert 1 2.
If dim is a scalar then c contains numel a size a dim cells.
If str2num cannot parse the input as numeric values then it returns an empty matrix.
A vector is simply a list of numbers.
The input can include spaces commas and semicolons to indicate separate elements.
If the length of vec is not a multiple of matcol then the function pads the last row of mat with zeros until the row contains matcol elements.
Matlab contains a built in function to reshape matrices that you can use to turn any matrix into a single row a vector.
A matrix is similar but contains multiple rows and columns of numbers.
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.
How can i do this.
Mat vec2mat vec matcol converts vector vec to matrix mat with matcol columns.
X str2num chr converts a character array or string scalar to a numeric matrix.
If dim is 1 or 2 then each cell contains a column or row vector respectively.
The kronecker tensor product if a is an m by n matrix and b is a p by q matrix then kron a b is an mp by nq matrix formed by taking all possible products between the elements of a and the matrix b.
If dim 2 then each cell contains an array whose dimth dimensional length is size a dim and whose other dimensions are all singletons.
If dim is not specified then c is the same size as a.
Hi i have to convert a matrix in one column row vector composed of all the rows of the original matrix.
