sumd is a k-by-1 vector, where element j is the sum of point-to-centroid distances within cluster j. By default, kmeans uses the squared Euclidean distance (see 'Distance' metrics). D— Distances from each point to every centroid numeric matrix Distances from each point to every ...
Using the "." will effectively perform element-by-element mathematical operations. So if you had 2 MxM matrices, say A and B, then: ThemeCopy C = A*B; Would yield normal matrix multiplication, while: ThemeCopy C = A.*B; Would yield element-by-element multiplication of both matrices. S...
Element-wise operations:These operations are done "element by element". If two vectors/matrices are to be added, subtracted, or element-wise multiplied or divided, they must have the same size. a=[1234]';% A column vector2*a% Scalar multiplicationa/4% Scalar divisionb=[5678]';% Another...
Computing the path loss involves scalar operations that work independently on each element of an array (known as element-wise), plus sum to add the x, y and z values along the 3rd dimension. distanceSquared = sum(pathToAntenna.^2, 3); % Syntax to sum along dim 3 distance = sqrt(dist...

To stretch the inputs, dtw repeats each element of x and y as many times as necessary. If x and y are matrices, then dist stretches them by repeating their columns. In that case, x and y must have the same number of rows. example [dist,ix,iy] = dtw(x,y) returns the common ...
