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 the Inequality operator ≠ and the Is Element Of operator 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.
