Arithmetic operators¶

Operator	Description	Example
`+`	Addition	`a + b` Adds `a` and `b`.
`-`	Subtraction	`a - b` Subtracts `b` from `a`.
`*`	Matrix Multiplication	`a * b` Multiplies `a` and `b` if `a` and `b` are matrices or vectors. If either operand is a scalar, element-by-element multiplication will be performed.
`.*`	ExE Multiplication	`a .* b` Multiplies elements of `a` and `b`.
`/`	Matrix Division	`a / b` Computes the least squares solution if `a` and `b` are matrices or vectors. If either operand is a scalar, element-by-element division will be performed.
`./`	ExE Division	`a ./ b` Divides each element of `a` by the corresponding element of `b`.
`.^`	ExE Power	`a .^ b` Raises each element of `a` to the power of `b`.
`'`	Transpose	`a'` Transposes matrix `a`, swapping its rows with columns.
`.'`	Bookkeeping Transpose	`a.'` Transposes matrix `a` without conjugation, applicable to complex matrices.
`=`	Assignment	`a = b` Assigns `b` to `a`.

Operator	Description	Example
`.==`	Element-by-Element Equality	`a .== b` Compares each element of `a` with `b`, resulting in a matrix of 1’s and 0’s.
`==`	Equality	`a == b` Returns a scalar 1 (true) if all elements of `a` and `b` are equal, otherwise 0 (false).
`=`	Inequality	`a != b` Returns a scalar 1 (true) if `a` and `b` are not equal, otherwise 0 (false).
`.!=`	Element-by-Element Inequality	`a .!= b` Compares each element of `a` with `b`, resulting in a matrix of 1’s and 0’s.
`.>=`	Element-by-Element Greater or Equal	`a .>= b` Compares each element of `a` with `b`, resulting in a matrix of 1’s and 0’s.
`>=`	Greater or Equal	`a >= b` Returns 1 (true) if all elements of `a` are greater than or equal to those of `b`, otherwise 0 (false).
`.<=`	Element-by-Element Less or Equal	`a .<= b` Compares each element of `a` with `b`, resulting in a matrix of 1’s and 0’s.
`<=`	Less or Equal	`a <= b` Returns a scalar 1 (true) if all elements of `a` are less than or equal to those of `b`, otherwise 0 (false).
