4-15 Logical Operators & and the find Function >>x = [5, -3, 0, 0, 8]; y = [2, 4, 0, 5, 7]; >>z = find(x&y) z = 1 2 5 Note that the find function returns the indices, and not the values. In the following session, note the difference between the result obtained by y(x&y) and the result obtained by find(x&y) in the previous example. >>values = y(x&y) values = 2 4 7 >>how_many = length(values) how_many = 3 Z.R.K
The if and else Statement The if statement’s basic form is if logical expression statements end Every if statement must have an accompanying end statement. The end statement marks the end of the statements that are to be executed if the logical expression is true. The basic structure for the use of the else statement is if logical expression statement group 1 else statement group 2 end Flowchart of the else structure.
