    • How to index an array in MATLAB?

      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.

    • How do I create a matrix in MATLAB?

      MATLAB - Matrix. A matrix is a two-dimensional array of numbers. In MATLAB, you create a matrix by entering elements in each row as comma or space delimited numbers and using semicolons to mark the end of each row.

    • What does IDX mean in MATLAB?

      idx is a vector of predicted cluster indices corresponding to the observations in X. C is a 3-by-2 matrix containing the final centroid locations. Use kmeans to compute the distance from each centroid to points on a grid. To do this, pass the centroids (C) and points on a grid to kmeans, and implement one iteration of the algorithm.

    • How to use Matlab?

      To start MATLAB from your Xterm window, simply type: matlab. You can either type commands directly into MATLAB, or put all of the commands that you will need together in a m-file, and just run the file. If you put all of your m-files in the same directory that you run MATLAB from, then MATLAB will always find them. Getting Help in MATLAB
