MATLAB Forum - Wie kann ich einen einfachen Vektor plotten X = ones (sz) returns an array of ones where the size vector, sz, defines size (X) . I've touched on the idea before, but now that we've seen what a transpose is, and we've taken transposes of matrices, there's no reason why we can't take the transpose of a vector, or a column vector in this case. For example, ones (5,'int8') returns a 5-by-5 matrix of 8-bit integers If any trailing dimensions greater than 2 have a size of 1, then the output, X, does not include those dimensions. The Matrix package contains functions that extend R to support highly dense or sparse matrices. Each entry in the array represents an element a i,j of the matrix and is accessed by the two indices i and j.Conventionally, i is the row index, numbered from top to bottom, and j is the column index, numbered from left to right. y = linspace(a,b) generates a row vector y of 100 points linearly spaced between and including a … in A.

This is a generic function for which methods can be written. Advertisements. While other programming languages mostly work with numbers one at a time, MATLAB® is designed to operate primarily on whole matrices and arrays. If you have a specific set of data, you can arrange the elements in a matrix using square brackets. sign of the imaginary parts. B = transpose(A) is B = A.' If the size of any dimension is negative, then it is treated as 0..
