MATLAB reshape Function

Syntax

(1) B = reshape (a, m, n)

Usage:
B = reshape (a, m, n) returns M * n matrix B. Its element is to get the row width of. If a does not have an M * nelement, an error is returned.

Example:

<span style="font-size:18px;">>> A=rand(1,10)</span>

Result:

<span style="font-size:18px;">A =  Columns 1 through 8    0.1622    0.7943    0.3112    0.5285    0.1656    0.6020    0.2630    0.6541  Columns 9 through 10    0.6892    0.7482</span>

<span style="font-size:18px;">>> B=reshape(A,5,2)</span>

Result:

B =    0.1622    0.6020    0.7943    0.2630    0.3112    0.6541    0.5285    0.6892    0.1656    0.7482

(2)

B = reshape (A, M, N, P ,...)

B = reshape (A, [m n p...])
Returns an n-dimensional array with the same elements as a, but its structure changes to M * n * p *...

For example:

<span style="font-size:18px;">>> A=rand(1,12)</span>

Result: matrix

A =  Columns 1 through 8    0.4505    0.0838    0.2290    0.9133    0.1524    0.8258    0.5383    0.9961  Columns 9 through 12    0.0782    0.4427    0.1067    0.9619

>> D=reshape(A,2,3,2)D(:,:,1) =    0.4505    0.2290    0.1524    0.0838    0.9133    0.8258D(:,:,2) =    0.5383    0.0782    0.1067    0.9961    0.4427    0.9619

(3)

B = reshape (A,..., [],...)

>> C=reshape(A,5,[])

Result:

C =    0.1622    0.6020    0.7943    0.2630    0.3112    0.6541    0.5285    0.6892    0.1656    0.7482

(4)

B = reshape (A, siz)

Returns an n-dimensional array with the same elements as a. however, according to siz, a vector transformed array dimension. The value prod (siz) must be the same as prod (SIZE (.
