Conditional Statements in Matlab Programming

A conditional statement is a system that allows for conditional execution of instructions based on the result of a conditional statement, which can either result true or false. Below is a flowchart of an if statement containing an optional else statement.
if expression
statements
elseif expression
statements
else
statements
end
If expression, statements, end results in an expression, and executes a set of statements when the expression is true. An expression is true when its result is non-empty and contains only non-zero elements (logical or real numeric). Otherwise, the expression is false. The else-if and else blocks are optional which may be use or not. The statements execute only if latter expressions in the if...end block are false. An if block can include more than one elseif blocks.
There are the various cases where conditional statements are used.

Compare Arrays

Expressions that makes use of relational operators on arrays, such as A > 0, are true only when every element in the result is non-zero. Test if any condition is true using the any function.

Test Arrays for Equality

Compare arrays using isequal in-place of the == operator to test for equality, because == results in an error when the arrays are of different sizes.

Compare Character Vectors

Use strcmp for comparison of character vectors. Using == to test for equality results an error when the character vectors are of different sizes.

Evaluate Multiple Conditions in Expression

Checks if a value lies within a specified range.
