Creating Matrices. MATLAB has many functions that create different kinds of matrices. For example, you can create a symmetric matrix with entries based on Pascal's triangle: A = pascal (3) A = 1 1 1 1 2 3 1 3 6. Or, you can create an unsymmetric magic square matrix, which has equal row and column sums: B = magic (3) newStr = extract (str,pat) returns any substrings in str that match the pattern specified by pat. If str is a string array or a cell array of character vectors, then the function extracts substrings from each element of str. If pat is an array, then the function matches against multiple patterns. newStr = extract (str,pos) returns the character ...

Terminate Conditional Statement and for Loop. Use end to close an if statement and a for loop. The first instance of end pairs with the if statement, and the second pairs with the for statement. a = [0 0 1 1 0 0 0 1 0]; for k = 1:length (a) if a (k) == 0 a (k) = 2; end end.Because two NaN s are not equal to each other, logical operations involving NaN always return false, except for a test for inequality, ( NaN ~= NaN ): NaN > NaN ans = 0 NaN ~= NaN ans = 1. MATLAB represents infinity by the special value inf, and values that are neither real nor complex by the special value NaN, which stands for “Not a Number”.a(end-4:end,:) a[-5:] last 5 rows of 2D array a. a(1:3,5:9). a[0:3, 4:9].

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. x = j:i:k creates a regularly-spaced ... Every variable in MATLAB® is an array that can hold many numbers. When you want to access selected elements of an array, use indexing. For example, consider the 4-by-4 matrix A:This partition divides the observations into a training set and a test, or holdout, set. example. c = cvpartition (group,"KFold",k) creates a random partition for stratified k -fold cross-validation. Each subsample, or fold, has approximately the same number of observations and contains approximately the same class proportions as in group.Format of the output fields, specified using formatting operators. formatSpec also can include ordinary text and special characters.. If formatSpec includes literal text representing escape characters, such as \n, then sprintf translates the escape characters.. formatSpec can be a character vector in single quotes, or a string scalar.. Formatting OperatorC = vertcat (A,B) concatenates B vertically to the end of A when A and B have compatible sizes (the lengths of the dimensions match except in the first dimension). example. C = vertcat (A1,A2,…,An) concatenates A1, A2, … , An vertically. vertcat is equivalent to using square brackets to vertically concatenate or append arrays.The end command also serves as the last index in an indexing expression. In that context, end = (size (x,k)) when used as part of the k th index. Examples of this use are X (3:end) …You can diagnose problems in your MATLAB ® code files by debugging your code interactively in the Editor and Live Editor or programmatically by using debugging functions in the Command Window.
