Webabcosφ, where a and b is the magnitudes of the two vectors and φ is the angle between the two vectors. When two vectors are in unit-vector notation, their dot product is written as: a ⋅ b = (a1i + a2j + a3k)⋅(b1i + b2j + b3k) and the result is a ⋅ b = a1b1 + a2b2 + a3b3. In MATLAB, you can compute the dot product using dot command. For ... WebMay 23, 2024 · User beaker pointed out that an even simpler (though a bit obscure) syntax works in recent versions of MATLAB. If you subtract a vector from a matrix, MATLAB will extend the vector to match the size of the matrix as long as one dimension of vector matches the matrix dimensions.
