# Function ctranspose Transpose and complex conjugate a matrix. All values of the matrix are reflected over its main diagonal and then the complex conjugate is taken. This is equivalent to complex conjugation for scalars and vectors. ## Syntax ```js math.ctranspose(x) ``` ### Parameters Parameter | Type | Description --------- | ---- | ----------- `x` | Array | Matrix | Matrix to be ctransposed ### Returns Type | Description ---- | ----------- Array | Matrix | The ctransposed matrix ## Examples ```js const A = [[1, 2, 3], [4, 5, math.complex(6,7)]] math.ctranspose(A) // returns [[1, 4], [2, 5], [3, {re:6,im:7}]] ``` ## See also [transpose](transpose.md), [diag](diag.md), [inv](inv.md), [subset](subset.md), [squeeze](squeeze.md)
