I would expect k to be a column vector of length size (A,1) with the i-th element of k giving the desired column index. Right now, I'm just using find () on each row inside of a for-loop:

Working With Multi-Dimensional Arrays; In MATLAB, the 'size' function is a fundamental tool used to determine the dimensions of arrays and matrices. It returns the number of rows and columns present in a given matrix, making it essential for data manipulation and analysis.

In order to assign a value to an array you need to tell matlab where in the array you want it to go. First, create an array of zeros the right size with. arr = zeros(1,10); Then you can assign count to element i of arr with. arr(i) …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. A = [1 4 7 10; 2 5 8 11; 3 6 9 12] A = 3×4 1 4 7 10 2 5 8 11 3 6 9 12. B = reshape (A,2,6) B = 2×6 1 3 5 7 9 11 2 4 6 8 10 12. As long as the number of elements in each shape are the same, you can reshape them into an array ...Every array in MATLAB has trailing dimensions of size 1. For multidimensional arrays, this means that a 3-by-4 matrix is the same as a matrix of size 3-by-4-by-1-by-1-by-1. Examples of multidimensional arrays with compatible sizes are: One input is a matrix, and the other is a 3-D array with the same number of rows and columns. As you know, matlab deals mainly with matrices. So, the size function gives you the dimension of a matrix depending on how you use it. For example: 1.
