Matlab reshape function

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. To do this, use the transpose function or the. A similar operator ' computes the conjugate transpose for complex matrices. This operation computes the complex conjugate of each element and transposes it. Create a 2-by-2 complex matrix and compute its conjugate transpose. You can shift elements of an array by a certain number of positions using the circshift function. For example, create a 3-by-4 matrix and shift its columns to the right by 2. The second argument [0 2] tells circshift to shift the rows 0 places and shift the columns 2 places to the right.

M has 18 elements. Vote 0.

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.
