Matlab Code - Loops, branches, and control-flowMATLAB code has its own instructions for control-flow statements like 'for-loops', 'while' and 'if-elseif' branching. Click on the links to see details and examples. For loop The for loop repeats a group of statements a fixed, predetermined number of times. A matching end delineates the statements. Application of Nested Iterations (Matrix Multiplication) We show a script in Matlab code that performs a matrix multiplication step-by-step. The algorithm displays all the elements being considered for the multiplication and shows how the resulting matrix is being formed in each step. Obviously, Matlab can do it with just one operation, but... While loop The while loop repeats a group of statements an indefinite number of times under control of a logical condition. A matching end closes the statements. If... elseif... else... end (branches or decisions) The if statement evaluates a logical expression and executes a group of statements when the expression is true. The optional elseif and else keywords provide for the execution of alternate groups of statements. Break The break statement lets you exit early from a for or while loop. In nested loops, break exits from the innermost loop only. Control Flow: for-loops, if-statements, break (in a Matrix Inversion) This program performs the matrix inversion of a square matrix step-by-step. The inversion is performed by a modified Gauss-Jordan elimination method. We start with an arbitrary square matrix and a same-size identity matrix (all the elements along its diagonal are 1)... Switch-Case-Otherwise The switch statement executes groups of statements based on the value of a variable or expression. The keywords case and otherwise delineate the groups.
