Apply element wise operation to two arrays with implicit expansion enabled collapse all in page syntax c = bsxfun (fun,a,b) description example c = bsxfun (fun,a,b) applies the element wise binary operation specified by the function handle fun to arrays a and b. examples collapse all deviation of matrix elements from column mean. Create two 3 by 3 arrays, a and b, and multiply them element by element. a = [1 0 3; 5 3 8; 2 4 6]; b = [2 3 7; 9 1 5; 8 8 3]; c = a.*b c = 3×3 2 0 21 45 3 40 16 32 18 multiply row and column vectors create a row vector a and a column vector b, then multiply them. the 1 by 3 row vector and 4 by 1 column vector combine to produce a 4 by 3 matrix. These are the relational operators in matlab ®. array comparison numeric arrays the relational operators perform element wise comparisons between two arrays. the arrays must have compatible sizes to facilitate the operation. arrays with compatible sizes are implicitly expanded to be the same size during execution of the calculation. Create a 1 by 2 row vector and 3 by 1 column vector and subtract them. a = 1:2; b = (1:3)'; a b ans = 3×2 0 1 1 0 2 1 the result is a 3 by 2 matrix, where each (i,j) element in the matrix is equal to a (j) b (i): a = [ a 1 a 2], b = [ b 1 b 2 b 3], a b = [ a 1 b 1 a 2 b 1 a 1 b 2 a 2 b 2 a 1 b 3 a 2 b 3]. Matlab language vectorization element wise operations example # matlab supports (and encourages) vectorized operations on vectors and matrices. for example, suppose we have a and b, two n by m matrices and we want c to be the element wise product of the corresponding elements (i.e., c (i,j) = a (i,j)*b (i,j) ).

Matlab ® has two different types of arithmetic operations: array operations and matrix operations. you can use these arithmetic operations to perform numeric computations, for example, adding two numbers, raising the elements of an array to a given power, or multiplying two matrices. matrix operations follow the rules of linear algebra. The logical operators return a logical array with elements set to true ( 1) or false ( 0 ), as appropriate. the & operator does a logical and, the | operator does a logical or, and ~a complements the elements of a. the function xor (a,b) implements the exclusive or operation. the truth table for these operators and functions is shown below. Use the special characters in this table to specify a folder path using a character vector or string. . \. name: slash and backslash. uses : file or folder path separation. description: in addition to their use as mathematical operators, the slash and backslash characters separate the elements of a path or folder.
