Let's say there are vectors: a <- c(1, 2, 3, 4, 5, 6, 7, 8, 9, 10) b <- c(1, 2, 3, 4) How to add all the elements of a ... yclically, so that the output is this result: 2, 4, 6, 8, 6, 8, 10, 12, 10, 12 If you can use slices, then it would be great

Hello everyone How to find the length of the basis vectors in the affine coordinate system? It is known that there are point ... the vertex C and has the legs |CA|=2, |CB|=3. Determine the lengths of the basis vectors {e1,e2} and the angles between them.

I'm writing a simple game with graphics(the ball bounces off the window borders and lines, which the user builds himself). I ... rly). I would be glad if someone could help me find the answer to this question. I have been suffering for more than a week(

I have a circle with a gradient, I need to cut it in half so that the center of the gradient does not shift. When you try to ... top of the white circle rectangle and contour processing Such a semicircle with such a gradient in the end you need to get

Good time of day. I need to convert a two-dimensional array to a one-dimensional one. I did this in a simple, elementary loop ... vec[counter] := a[i, j]; ListBox1.Items.Add(inttostr(vec[counter])); counter := counter + 1; end; end;

You need to specify a vector consisting of functions, for example: g = @(x, y) x.^2 + y.^2; f = @(x, y) x.^3 + y.^4; It i ... the vector. So that you can specify a vector of functions as a parameter in a custom function. How to write this in Matlab?
