| There is an important difference between the [[LinearAlgebra/Transposition|transposition]] operators `'` and `.'`. The former is the ''complex conjugate'' transposition or ''Hermitian'' 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. For real numbers, the two are equivalent. Lastly, note that the function `transpose()` matches `.'`. |
MATLAB Operators
These are the operators supported by MATLAB.

Description
Most operators work as expected.
For the most part, prefixing an operator with a dot (.) causes element-wise operation. For example:
.* for element-wise multiplication
./ for element-wise right division
.\ for element-wise left division
.^ for element-wise power
There is an important difference between the transposition operators ' and .'. The former is the complex conjugate transposition or Hermitian 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. For real numbers, the two are equivalent. Lastly, note that the function transpose() matches .'.
