If Statement (Mlmode)

Syntax	if expression       list of statements  elseif expression      list of statements  else expression      list of statements  end
O-Matrix Mode	if

Description
Each if token begins a block without needing the begin keyword. If any element of the expression following the if is zero, the expression is considered false. In addition, the keyword elseif can be used to terminate one block and begin another.

Note that when an if is input at the command line, execution will not occur until the corresponding end is entered.

Example
If in Mlmode you enter
     x = 1;
     if x <= 0 
          0
     elseif x <= 1
          1
     else
          2
     end
O-Matrix will reply
     1


If you enter
     x = [ 1 0 ];
     if x
          1
     else
          2
     end
O-Matrix will respond
     2
