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.

If so, then what you would need to get reshape in matlab per epoch x 8 columns x 89 epochs, would be to reorder some of the data in memory. The elements in B also maintain their columnwise order from A.

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. Reshape the 2-by-6 symbolic matrix M into a 4-by-3 matrix. M and N must have the same number of elements.

Tags matlab reshape. In order to know how to get the order you want, you need to know whether the order of your data in memory is 89 related data values, with groups of that, and 8 columns across, or if the order of your data in memory is related data values, with 89 groups of that, and 8 columns across.
