## Logical Subscripting

Matlab Logical Subscripting Tutorial The logical vectors created from logical and relational operations can be used to reference subarrays. Suppose X is an ordinary matrix and L is a matrix of the same size...

## The find Function

Find Function The find function determines the indices of array elements that meet a given logical condition. In its simplest form, find returns a column vector of indices. Transpose that vector to obtain a...

## The magic Function

Matlab MAGIC Function MATLAB actually has a built-in function that creates magic squares of almost any size. Not surprisingly, this function is named magic. B = magic(4) B = 16 2 3 13 5...

## Subscripts

Subscripts Command The element in row i and column j of A is denoted by A(i,j). For example, A(4,2) is the number in the fourth row and second column. For our magic square, A(4,2)...

## bsxfun

bsxfun – Apply element-by-element binary operation to two arrays with singleton expansion enabled Syntax C = bsxfun(fun,A,B) Description C = bsxfun(fun,A,B) applies an element-by-element binary operation to arrays A and B, with singleton expansion...

## arrayfun

arrayfun – Apply function to each element of array Syntax A = arrayfun(fun, S) A = arrayfun(fun, S, T, …) [A, B, …] = arrayfun(fun, S, …) [A, …] = arrayfun(fun, S, …, ‘param1’,...

## idivide

idivide – Integer division with rounding option Syntax C = idivide(A, B, opt) C = idivide(A, B) C = idivide(A, B, ‘fix’) C = idivide(A, B, ’round’) C = idivide(A, B, ‘floor’) C =...
