Web2 days ago · For example, multiplying the vector SHAPE with the vector CIRCLE binds the two into a representation of the idea “SHAPE is CIRCLE.” This new “bound” vector is nearly orthogonal to both SHAPE and CIRCLE. ... it involves rearranging the individual elements of the vectors. For example, if you have a three-dimensional vector with values ... WebOct 23, 2013 · a*b doesn't work because you can't multiply a 7x1 vector by a 7x1 vector. As has been mentioned in the comments, a*b' works (because now you are multiplying a 7x1 vector by 1x7 vector, resulting in a 7x7 matrix), and so does a.*b (element-wise multiplication). Here's what I get with Octave 3.6.2:
