Reshape a 3-by- 4 matrix into a 2-by- 6 matrix. For example, reshape a 3-by-4 matrix to a 2-by-6 matrix. The quantity prod(siz) must be the same as prod(size(A)). The reshape function changes the size and shape of an array. ![]() The elements in B preserve their columnwise ordering from A. The data type and number of elements in B are the same as the data type and number of elements in A. Since you desire the elements to be populated by rows, a trick is to simply transpose the result. Therefore, just using reshape by itself will place the elements in the columns. The matrix is created in column-major order. Returns an N-D array with the same elements as A, but reshaped to siz, a vector representing the dimensions of the reshaped array. Reshaped array, returned as a vector, matrix, multidimensional array, or cell array. reshape transforms a vector into a matrix of a desired size. ![]() The value of prod(size(A)) must be evenly divisible by the product of the specified dimensions. The product of the specified dimensions, m*n*p*., must be the same as prod(size(A)).ī = reshape(A.) calculates the length of the dimension represented by the placeholder, such that the product of the dimensions equals prod(size(A)). mat vec2mat (vec,matcol) converts the vector vec into a matrix with matcol columns, creating one row at a time. Returns an N-D array with the same elements as A but reshaped to have the size m-by- n-by- p-by. An error results if A does not have m*n elements.ī = reshape(A,m,n,p.) or B = reshape(A,) ![]() Returns the m-by- n matrix B whose elements are taken column-wise from A.
