  # Matlab Code - Loops, branches, and control-flow

The MATLAB code has its own instructions for flow of control statements like 'for-loops', 'while' and 'if-elseif' branching. 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...

Pascal's Triangle
Let's calculate the coefficients of binomial expansions...

Armstrong Numbers
An Armstrong number (sometimes called also narcissistic numbers) of three digits is an integer such that the sum of the cubes of its digits equals the number itself. For example, 407 is an Armstrong number since 4^3 + 0^3 + 7^3 = 407...

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...

Square Root (using while-loops)
We’ll explore a square root algorithm as an excuse to use while-loops in our numerical software. We’re not going to use the built-in function ‘sqrt’...

Collatz Sequence (while-loops)
The Collatz conjecture is an unsolved conjecture in mathematics. This conjecture is also known as 3n + 1 or the Syracuse problem; the sequence of numbers involved is referred to as the hailstone sequence...

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 (exit from loops)
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...

Piecewise Functions
piecewise function (or piecewise-defined function) is a function whose definition changes depending on the value of the independent variable...

Equation of Straight lines
We'll develop three functions to work out equations of straight lines in Matlab with different approaches...
