Here is an example showing if, else, and elseif. Exactly one of the four assignments to x is executed, depending upon the values of the three logical expressions, A, B, and C. expression is a MATLAB expression, usually consisting. The two segments shown below produce identical results. MATLAB - if. Statements An if can have zero or one elses and it must come after any elseifs. if expression1 statements1 elseif expression2 statements2 else statements3 end.
The latter is used in a linear sequence of conditional statements with only one terminating end. The optional elseif and else keywords provide. It also introduces MATLABs input command which enables data to be input from the keyboard. The former introduces a new, nested if, which must have a matching end. The if statement evaluates a logical expression and executes a group of statements when the expression is true. commands evaluated if no other expression is true. If the logical expression is true (that is, if it evaluates to logical 1), MATLAB. For nonscalar expressions, (for example, is matrix A less then matrix B), true means that every element of the resulting matrix has a logical true or nonzero value.Įxpressions usually involve relational operations such as (count = 0).Įlse if, with a space between the else and the if, differs from elseif, with no space. or false, use the if statement (which may include else or elseif). If expression1 evaluates as false and expression2 as true, MATLAB executes the one or more commands denoted here as statements2.Ī true expression has either a logical true or nonzero value. Elseif (MATLAB Functions) MATLAB Function Reference Hello, I have just gotten back into matlab and I am practicing the else if statememts.
