The sibling function logspace generates logarithmically spaced values when you create a vector to index into a cell array or structure array such as cellname. The code itself has to be in fortran, which is the language for scientific programming. This matrix is then multiplied with c to arrive at the 500by2 result. Learn more about vactor, gui, edit, text, callback. Follow 493 views last 30 days jelmer hoogendoorn on 8 mar 2011. Builtin integers are treated as fixedpoint objects. Matlab uses the characters i and j to represent imaginary units. A quiver plot displays velocity vectors as arrows with components u,v at the points x,y for example, the first vector is defined by components u1,v1 and is displayed at the point x1,y1 quiverx,y,u,v plots vectors as arrows at the coordinates specified in each corresponding pair of elements in x and y. Depending on the dimension of coordinate axis, vectline can plot both 3d and 2d vector field line. Mit dem befehl quiver kann man in matlab vektorfelder graphisch darstellen. The function can plot both 2d and 3d vector with arrow depending on the dimension of the input.

Prinzipiell kann matlab mit matrizen parallel rechnen, es sollte. The sizes of a and b must be the same or be compatible if the sizes of a and b are compatible, then the two arrays implicitly expand to match each other. The vector is treated as though it is a matrix of the same size as a, so that each element in the vector is added to a row in a. Lecture 1 vectors, functions, and plots in matlab in these notes. Therefore, the cumsum operation on a gpuarray might not return exactly the same answer as the cumsum operation on the corresponding matlab numeric array.
