Web4 jul. 2024 · In MATLAB the array indexing starts from 1. To find the index of the element in the array, you can use the find () function. Using the find () function you can find the indices and the element from the array. The find () function returns a vector containing the data. Syntax: find (X) : Return a vector containing the indices of elements WebMATLAB numbers indices from 1; a(1) is the first element. See note INDEXING. NumPy, like Python, numbers indices from 0; a[0] is the first element. MATLAB’s scripting language was created for linear algebra so the syntax for some array manipulations is …

WebTo get the linear indices of matrix elements that satisfy a specific condition for matrix A, you can use the find function with one output argument. To get the subscript indices, use the find function with two output arguments. For example, [row,col] = ind2sub(size(A),find(A>5)) gives the same result as [row,col] = find(A>5). Web11 mrt. 2015 · To do ind2sub, you'd want the unravel_index function. The first input is an array of linear indices that you want converted into locations of each dimension in your array. The second input is a tuple of dimensions like previously. I'm going to leave the post at the bottom for posterity, in case you want to try and implement these yourself.

WebExample. MATLAB allows for several methods to index (access) elements of matrices and arrays: Subscript indexing - where you specify the position of the elements you want in each dimension of the matrix separately.; Linear indexing - where the matrix is treated as a vector, no matter its dimensions.
