Additional elseif statements and/or an else statement may be used.

Here is an example showing if, else, and elseif. MATLAB uses if paired with a matching end to provide conditional execution of statements. When nesting ifs, each if must be paired with a matching end.

Exactly one of the four assignments to x is executed, depending upon the values of the three logical expressions, A, B, and C. MATLAB evaluates the expression and, if the evaluation yields a logical true or nonzero result, executes one or more MATLAB commands denoted here as statements. The two segments shown below produce identical results. The latter is used in a linear sequence of conditional statements with only one terminating end. The following is easily extendable to more dataa1 6 2. and so on then plot L1, L2.2 answers 0 votes: Do more vectorized processing.

The former introduces a new, nested if, which must have a matching end. but now i want to add case 4 which will plot all three case in one graph i can do it by calling a1,a2,a3. MATLAB doesn't have conditional expressions, but in some situations you can get a similar effect by saying, e.g., var condtrueexpr + (1-cond)falseexpr.Unlike C's conditional expression, this will of course always evaluate both trueexpr and falseexpr, and if cond happens not to be either 0 or 1 (note: false behaves like 0 true behaves like 1) you'll get crazy results. 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. 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.
