Operator
Description
Keyboard Shortcut
Returns 1 if x is an element of the number set y, returns 0 otherwise.
Returns 1 if x is equal to y, 0 otherwise.
Returns 1 if x is greater than y, 0 otherwise.
>
Returns 1 if x is greater than or equal to y, 0 otherwise.
>=
Ctrl+0
Returns 1 if x is less than y, 0 otherwise.
<
Returns 1 if x is less than or equal to y, 0 otherwise.
<=
Ctrl+9
Returns 1 if x is not equal to y, 0 otherwise.
< >
Operands
x, y are real or imaginary scalars, vectors or matrices, or strings. x and y must be of the same type. If x and y are arrays, they must have the same number of rows and columns.
Additional Information
• The comparison operators are affected by the worksheet’s Calculation Options.
• Apart from ≠ and Є, you can use the comparison operators for specifying constraints in solve blocks.
• The equal to operator is useful for defining expressions that you do not wish to evaluate, as it does not yield a result until an evaluation operator is applied.
• When a scalar is compared to an array, or when two arrays are compared to each other, the comparison is performed element-wise.
• String comparisons result in alphabetical sorting.
• To compare term-by-term two arrays of equal size, select the entire expression and insert the vectorize operator.
