### Decisions, Part 1

• if: the if construct, which is fundamental to all computing languages, is the basis for a decision making. The simple form of if in a single line is:
• if condition statement, end
• Note that conditions are usually a logical expression, which are either true or false. If condition is true, statement is executed, otherwise nothing happens. Condition maybe a vector or matrix, in which case it is true if all its elements are non-zero.
• The basic if-else form is:
• if condition
• statements A
• else
• statements B
• end
• On the other hand we can have elseif and use it like a ladder:
• if condition1
• statementsA
• elseif condition2
• statementsB
• elseif condition3
• statementsC
• ...
• else
• statementsE
• end
