Julia Operators

These are the operators supported by Julia.

Description

Most operators work as expected. Note that / performs floating point division whereas // performs exact rational division.

For the most part, prefixing an operator with a dot (.) causes element-wise operation. For example:

• .* for element-wise multiplication

• ./ for element-wise division

• .^ for element-wise power

To type the cross product operator, type \times and tab-complete. This is equivalent to calling the cross() function on two vector arguments.

Similarly, for the dot product operator, type \cdot and tab-complete. This is equivalent to calling the dot() function on two vector arguments.

There is an important difference between the transposition operator ' and the function transpose(). The former gives the complex conjugate transposition, by which a complex number as a + bi is transposed to a - bi. The latter is the non-conjugate transposition and does not flip any signs.
