Description. 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.

tf = logical(cond) checks if the conditions in cond are true and returns an array of logical values. To test conditions that require assumptions or mathematical transformations, use isAlways instead.
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') b = a/2; end.
If the evaluated expression yields a nonscalar value, then every element of this value must be true or nonzero for the entire expression to be considered true. For example, the statement, if (A < B) is true only if each element of matrix A is less than its corresponding element in matrix B .
20 Ιουν 2011 · If an element of X is nan, or an element of Y is nan, then you'll get a NaN in A, irrespective of the condition. Really Useful corollary: you can use bsxfun where COND and X / Y have different sizes. A = bsxfun( @times, COND', X ) + bsxfun( @times, ~COND', Y );
Give MATLAB code to calculate y where y = -1 when x < 0 and y = 2 when x > 2. The statement y = -1 is executed only if the condition x<0 is true. The statement y = 2 is executed only if the condition x<0 is false and the condition x>2 is true.
This MATLAB function evaluates an expression, and repeats the execution of a group of statements in a loop while the expression is true.
