Matlab reshape function

Help Center Help Center. For example, reshape A,[2,3] reshapes A into a 2-by-3 matrix. You can specify a single dimension size of [] to have the dimension size automatically calculated, such that the number of elements in B matches the number of elements in A. For example, if A is a by matrix, then reshape A,2,2,[] reshapes the elements of A into a 2-byby array. Reshape a 4-by-4 square matrix into a matrix that has 2 columns. Specify [] for the first dimension to let reshape automatically calculate the appropriate number of rows. The result is an 8-by-2 matrix, which maintains the same number of elements as the original matrix. The elements in B also maintain their columnwise order from A. Data Types: single double int8 int16 int32 int64 uint8 uint16 uint32 uint64 logical char string cell struct datetime duration calendarDuration Complex Number Support: Yes. Output size, specified as a row vector of integers. 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.

For example, if A is a by matrix, then reshape A,2,2,[] reshapes the elements of A into a 2-byby array. When you use [] to automatically calculate a dimension size, the dimensions that you do explicitly specify must divide evenly into the number of elements in the input matrix, matlab reshape function, numel A.

Help Center Help Center. This can be helpful for preprocessing your data for subsequent computations or analyzing the data. The reshape function changes the size and shape of an array. For example, reshape a 3-by-4 matrix to a 2-by-6 matrix. As long as the number of elements in each shape are the same, you can reshape them into an array with any number of dimensions. Using the elements from A , create a 2-byby-3 multidimensional array. A common task in linear algebra is to work with the transpose of a matrix, which turns the rows into columns and the columns into rows.

The elements are taken column-wise from A to fill in the elements of the n1 -by For example, if A has size 2-by-6, then reshape A,4,[] returns a 4-by-3 array. Reshape V , which is a 1-by-4 row vector, into the 4-by-1 column vector Y. Here, V and Y must have the same number of elements.

Vote 0. Use reshape to break up the vector V to find the product of every three elements. Suppose I have a colored image of 64x Unable to complete the action because of changes made to the page. Reshape a vector to a matrix. Example: reshape A,[6,4,10]. Version History Introduced before Ra. See Also. Suppose, if I put. Toggle Main Navigation. Search MathWorks. Thanks for the tips. The elements are taken column-wise from A to fill in the elements of the n1 -by- n2 matrix. Input array, specified as a symbolic vector, matrix, or multidimensional array.

Create a matrix A and sort each column of A in ascending order. If you provide an empty matrix as dimension, the other given dimensions are used and the missing one is replaced such, that the total number of elements is not modified. Select the China site in Chinese or English for best site performance. The first dimension input should always be empty, such as reshape X,[],M,N, Create the matrix M. Yeah that makes sense, but it gives the order of the values in the wrong orientation. Accepted Answer: Wan Ji. Based on your location, we recommend that you select:. Output Arguments collapse all B — Reshaped array vector matrix multidimensional array cell array. Reshape the 2-by-6 symbolic matrix M into a 4-by-3 matrix. I recommend that you work backwards from the solution. A common task in linear algebra is to work with the transpose of a matrix, which turns the rows into columns and the columns into rows. Create a 2-by-2 complex matrix and compute its conjugate transpose.
