if expression, statements, end evaluates an expression, and executes a group of statements when the expression is true. An expression is true when its result is nonempty and contains only nonzero elements (logical or real numeric). Otherwise, the expression is false. The elseif and else blocks are optional.
Conditional Statements. Conditional statements enable you to select at run time which block of code to execute. The simplest conditional statement is an if statement. For example: % Generate a random number. a = randi(100, 1); % If it is even, divide by 2. if rem(a, 2) == 0. disp('a is even')
switch switch_expression, case case_expression, end evaluates an expression and chooses to execute one of several groups of statements. Each choice is a case. The switch block tests each case until one of the case expressions is true. A case is true when: For numbers, case_expression == switch_expression.
Description. for index = values, statements, end executes a group of statements in a loop for a specified number of times. values has one of the following forms: initVal:endVal — Increment the index variable from initVal to endVal by 1, and repeat execution of statements until index is greater than endVal.
Copy. if FreqSec (1,r+1) > FreqSec (r)*1.01 || FreqSec (1,r+1) <FreqSec (r)*0.99. The first of these is more general. The second of these, , is the short-circuiting OR that does not bother to evaluate the second expression if it already knows the final result after the first operation. The operator can only be used between expressions that ...
This MATLAB function performs a logical AND of inputs A and B and returns an array or a table containing elements set to either logical 1 (true) or logical 0 (false).
So, although the statement 1|[] evaluates to false, the same statement evaluates to true when used in either an if or while expression" The idea of the warning (as I understand the reasoning) is that relying on conversion from array to scalar in an if/while is a bad idea.
Here are three ways to display multiple variable values on the same line in the Command Window. Concatenate multiple character vectors together using the [] operator. Convert any numeric values to characters using the num2str function. Use disp to display the result. X = [name, ' will be ',num2str(age), ' this year.'];
Description. while expression, statements, end evaluates an expression, and repeats the execution of a group of statements in a loop while the expression is true. An expression is true when its result is nonempty and contains only nonzero elements (logical or real numeric). Otherwise, the expression is false. example.
Extend long program lines using ellipses (...). Continue Long Statements on Multiple Lines. This example shows how to continue a statement to the next line using ellipsis (...
