The numerator is just a simple dot product between two vectors, and the denominator is just a simple sum. Using the fact that a dot product between two vectors can be accomplished with the matrix multiply operator, you can just do a (row vector) * (column vector) oper...
It's actually fortunate that you can avoid bsxfun. If B is an M x N matrix, then using bsxfun will require M*N multiplications, whereas with what I propose, you only do M multiplications.
Similarly, adding a vector v to one or more points X is vadd(X,v) instead of X + repmat(v,size(X,1),1) Where possible, the utility functions will automatically handle lists of elements, arbitrary dimension, and sometimes even ordering (for exmaple the matrix-vector multiply mulv produce...
MATLAB Courseware - Intro to Engineering course I am trying to solve this problem of plotting the motion of a projectile against time at five given angles. But I keep getting errors. I understand the error, it is happening because there are only five val...

In contrast, the .* operator performs elementwise multiplication and allows you to multiply the corresponding elements of two equally sized arrays. z = [3 4] .* [10 20] z = 30 80 奇奇怪怪的运算: https://www.mathworks.com/help/matlab/matlab_prog/compatible-array-sizes-for-basic-operation...
We can achieve this by sorting the diagonal elements of the matrix returned by eig().% Define the matrix Matrix = magic(3); % Find eigenvalues [EigenVectors, EigenValues] = eig(Matrix); % Sort eigenvalues [SortedValues, Indices] = sort(diag(EigenValues)) ...
