Description

The Convert 1-D to 2-D block reshapes a length-M_i 1-D vector or an M_i-by-N_i matrix to an M_o-by-N_o matrix, where M_o is specified by the Number of output rows parameter, and N_o is specified by the Number of output columns parameter.

y = reshape(u,Mo,No)         % Equivalent MATLAB code

The input is reshaped columnwise, as shown in the two cases below. The length-6 vector and the 2-by-3 matrix are both reshaped to the same 3-by-2 output matrix.

An error is generated if (M_o*N_o)(M_i*N_i). That is, the total number of input elements must be conserved in the output.

The output is frame-based if the Frame-based output check box is selected; otherwise, the output is sample-based.

Dialog Box

Number of output rows

The number of rows, M_o, in the output matrix.

Number of output columns

The number of rows, N_o, in the output matrix.

Frame-based output

Creates a frame-based output when selected.
