It allows you to do many things in one click.Apr 18, 2015 · Tilde ~ is the NOT operator in Matlab, and it has nothing special with images, it just treats them as matrices. ~ as operator return a boolean form of the matrix it's called against, that the result matrix is 1 for 0 in the original matrix and 0 otherwise. Examples: a = magic (2) a = 1 3 4 2 ~a ans = 0 0 0 0. another: This tutorial has tried to give both type of examples where they differed in their syntax. Consider following example where MATLAB and Octave make use of different functions to get the area of a curve: f (x) = x 2 cos (x) for −4 ≤ x ≤ 9. Following is MATLAB version of the code −. a = 8*cos (4) + 18*cos (9) + 14*sin (4) + 79*sin (9) Area ...Description. continue passes control to the next iteration of a for or while loop. It skips any remaining statements in the body of the loop for the current iteration. The program continues execution from the next iteration. continue applies only to the body of the loop where it is called. In nested loops, continue skips remaining statements ... A function handle is a MATLAB ® data type that represents a function. A typical use of function handles is to pass a function to another function. For example, you can use function handles as input arguments to functions that evaluate mathematical expressions over a range of values. Function handles can represent either named or anonymous ...

X = ones (sz) returns an array of ones where the size vector, sz, defines size (X) . For example, ones ( [2,3]) returns a 2-by-3 array of ones. example. X = ones ( ___,typename) also specifies the data type (class) of X for any of the previous syntaxes. For example, ones (5,'int8') returns a 5-by-5 matrix of 8-bit integers.Description. The colon is one of the most useful operators in MATLAB ® . It can create vectors, subscript arrays, and specify for iterations. example. x = j:k creates a unit-spaced vector x with elements [j,j+1,j+2,...,j+m] where m = fix (k-j). If j and k are both integers, then this is simply [j,j+1,...,k]. example. Description. x = A\B solves the system of linear equations A*x = B. The matrices A and B must have the same number of rows. MATLAB ® displays a warning message if A is badly scaled or nearly singular, but performs the calculation regardless. If A is a square n -by- n matrix and B is a matrix with n rows, then x = A\B is a solution to the ...MATLAB - Matrix Multiplication. Consider two matrices A and B. If A is an m x n matrix and B is an n x p matrix, they could be multiplied together to produce an m x p matrix C. Matrix multiplication is possible only if the number of columns n in A is equal to the number of rows n in B. In matrix multiplication, the elements of the rows in the ...
