# row and column in matrix matlab

Hello all i need help in finding the best row/column in a binary matrix. suppose i have a matrix of size 10050 containing only 1s and 0s, how can i find (using matlab)which row or column has highest number of ones? zeros and ones are randomly distributed in the matrix MATLAB is written to work with vectors and matrices the name MATLAB is short for Matrix Laboratory. A matrix looks like a table with rows and columns an m by n (or m x n) matrix has m rows by n columns (these are the dimensions of the matrix). Also, in MATLAB vectors can be either row vectors, e.g (1, 2, 3) or column vectors (1, 2, 3)T (where T is the transpose of a vector or matrix).Generates a matrix with m rows and n columns of copies of A. (If n m the third argument is not needed.) Perform the operation given by the function handle MATRIX NOTATION. Matrices in MATLAB can be represented by any symbol or string of symbols, such as A, a, MAT, RGB, realmat, and so on.In other words, a matrix is an array of symbols, consisting of M rows and N columns. MATLAB provides a function called sub2ind that converts from row and column subscripts to linear indices.Example 1: Shifting the rows of a matrix A MATLAB user recently posed this question in the comp.soft-sys. matlab newsgroup. Tutorial on matrix indexing in MATLABHow can I extract rows, columns, elements from a MATLAB matrix?Can you show me some examples of MATLAB matrix indexing?Here the first end is 4 and the second end is 5, since matrix A has four rows and five columns. Creating Matrix (or two dimensional array) of different sizes in Matlab. How to show a particular entry of a matrix. Transpose, size and inverse of a matrix.The general form of a 3x3 matrix (matrix with 3 rows and 3 columns) is. Matrices can be used as mathematical objects, or as collections of (vector) data.

The appropriate use of MATLAB syntax to distinguish between these applications is highlighted. for matrix X, returns the number of rows and columns in X as separate output variables. Recommendindexing - Find row and columns of matrix index in MATLAB.Recommendmatrix - change entire column and row in Matlab. Its name is derived from MATrix LABoratory. MATLAB has since been expanded and now has built-in functions for solving problems requiring data A portion of a matrix can be extracted and stored in a smaller matrix by specifying the names of both matrices and the rows and columns to extract. This article covers how to create matrices, vectors, and cell arrays with the programming software MATLAB.
