Pass this input vector as an argument to the transpose function.Initialize the input vector with 5 elements.In this example, we will use the transpose function to compute the transpose of a vector with 5 elements. Next, we will use the transpose function to compute the transpose of a vector input. In the above 4 examples, we have used a matrix as our input to the transpose function. In this example, we will use the transpose function to compute the transpose of a 2 x 3 real matrix.Īs we can see in the output, the transpose function has interchanged the rows and columns of our non-square input matrix. Next, we will use a non-square matrix as input to the transpose function. In the above 3 examples, we have used a square matrix as our input. Initialize the input matrix with complex elements.Īs we can see in the output, the transpose function has interchanged the rows and columns of our input complex matrix.In this example, we will use the transpose function to compute the transpose of a 3 x 3 complex matrix. Next, let us take an example where our input matrix will have complex elements as well. In the above 2 examples, our input matrix was of real elements. Pass this input matrix as an argument to the transpose function.Īs we can see in the output, the transpose function has interchanged the rows and columns of our input matrix.In this example, we will use the transpose function to compute the transpose of a 3 x 3 real matrix.
