Then, reshape is used to restructure this new matrix to the desired output matrix. To interlace two matrices together, a new array is explicitly constructed which puts the elements from the original matrices into the necessary order. Thus, when you reshape, the elements will still appear in the same order but are just “re-flowed” to the new shape of the matrix: The reshape command restructures the matrix to a different size but the order of the indices of the individual elements is unchanged. This indexing order continues until reaching the end of the array. MATLAB indexes elements along the first dimension of the matrix (which is rows) until it reaches the end of the first dimension (bottom row) and then loops back to the top row but at a new column.

The elements will appear in the internal MATLAB indexing order, which stores each column contiguously one after another. You can access individual elements in the array:Īnd you can make a 1D array out of a 2D array by “flattening” it:Ī_ = a(:) creates a 1D vector representation of a, with elements appearing in the index order. Example 1: reshape matlab A 1:10 B reshape(A,5,2) Example 2: reshape image matlab Read image in current directory Iimread('Flower. All arrays are stored in a specific way, with element indexes having a specific order. Let's check the examples of reshape image matlab. So you can just look at the examples and use those for inspiration. Each array element, no matter if it is a 1D, 2D or multi-dimensional array, can be accessed by a 1D index number. 1It takes an array and then an array for the dimensions. You are given an m x n matrix mat and two integers r and c representing the number of rows and the number of columns of the wanted reshaped matrix. % swap rows and cols but keep the 3rd dimension intact.To explain why the above operations work, it is necessary to understand how MATLAB internally indexes arrays. In MATLAB, there is a handy function called reshape which can reshape an m x n matrix into a new one with a different size r x c keeping its original data.
