MATLAB has many functions that help create matrices with certain values or a particular structure. For example, the zeros and ones functions create matrices of all zeros or all ones.
k = find(X) returns a vector containing the linear indices of each nonzero element in array X. If X is a vector, then find returns a vector with the same orientation as X. If X is a multidimensional array, then find returns a column vector of the linear indices of the result. example.
Creating a matrix is as easy as making a vector, using semicolons (;) to separate the rows of a matrix. A = [1 2 0; 2 5 -1; 4 10 -1] A = 3×3 . 1 2 0. 2 5 -1. 4 10 -1. We can easily find the transpose of the matrix A. B = A' B = 3×3 .
Learn to create arrays in MATLAB with concatenation to build new matrices from existing ones, array creation functions, reshaping arrays, and indexing to extract submatrices.
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. For example, let us create a 4-by-5 matrix a −
Create a matrix A with elements 1, 2, 3 in the first row and elements 4, 5, 6 in the second row. Square brackets are used to create a matrix. The elements in a row may be separated either by blanks or commas. Rows may be separated either by semicolons or newlines.
In MATLAB, you can create a matrix by entering the elements in each row as comma. You can also create a matrix with space delimited numbers and by using the semicolons to mark the end of each row. Matrix with single row. Let us create a simple matrix in MATLAB that has a single row and three elements. Each element should have a space or comma ...
