To sum up, if you intend to calculate the Hermitian conjugate, the complex conjugate transpose, then use ' (without the period). We see, that in addition to the transposition, the complex values have been transformed to their complex conjugates as well. The output is as expected, the transposed form of C. Let's take the transpose using the shorthand. What "correct" is depends on your application.Ĭonsider the following example of a matrix C containing complex numbers: > C =
But as soon as we deal with complex numbers, we will inevitably run into problems if we do not use the "correct" shorthand. As long as the transposed vector or matrix is real-valued, the two operators produce the same result. If you would only write ' (without the point), you are in fact using the ctranspose command instead, which calculates the complex conjugate transpose, which is also known as the Hermitian conjugate, often used in physics. Just as = becomes an evaluation of the eq function, think of. Like other MATLAB commands, these operators are "syntactical sugar" that gets turned into a "proper" function call at runtime. The two commands are very similar, but conceptually very distinct. * multiplies elements of matrices together. This is in keeping with the syntax for the other element-wise operations in MATLAB: * multiplies matrices. ', there is a period in front of the apostrophe. Hermitian conjugate) of a vector or matrix in MATLAB. ' is the correct way to take the complex conjugate transpose (a.k.a.' is the correct way to transpose a vector or matrix in MATLAB. Ordinary Differential Equations (ODE) Solvers.Fourier Transforms and Inverse Fourier Transforms.What you see is NOT what you get: char vs cellstring in the command window.Using `length` for multidimensional arrays.output vector/matrix transpose (input vector/matrix) The function takes an input vector or a matrix as an argument and returns the transpose. Undefined Function or Method X for Input Arguments of Type Y The MATLAB has a built-in transpose function which when applied on any vector or matrix, it directly computes and returns the transpose of a matrix.
The use of "i" or "j" as imaginary unit, loop indices or common variable.Do not name a variable with an existing function name.
