Hi, Is there built in Math function is available to find the cross or dot product of two vectors?. Thanks PSB Python 11 4944 Cross platform way of finding number of processors on a machine? by: John | last post by: Is there a way to find the number of processors on a machine...
corr finds a dot product between vectors (v1, v2). If it works bad with your signal, I'd try to minimize a sum of squares of differences (i.e. abs(v1 - v2)). signal = sin(1:100); signal1 = [zeros(1, 10) signal]; signal2 = [signal zeros(1, 10)]; for i = 1:length...
As I told you in my comment, I think you made a mistake somewhere. The vectors actually contain the<word,frequency>pairs, notwordsonly. Therefore, when you delete the sentence, only the frequency of the corresponding words are subtracted by 1 (the words after are not shifted). Consider the...
0 <= dot(AB,AM) <= dot(AB,AB) && 0 <= dot(BC,BM) <= dot(BC,BC) AB is vector AB, with coordinates (Bx-Ax,By-Ay), and dot(U,V) is the dot product of vectors U and V: Ux*Vx+Uy*Vy. Update. Let's take an example to illustrate this: A(5,0) B(0,2) C(1,5)...

Haven't been able to (in my opinion) come up with anything sensible. Essentially, I have noticed that if we denote rows of A and columns of X as vectors, such thata1=(a1,1,a1,2,a1,3,a1,4)(by row up to a3) andx1=(x1,1,x2,1,x3,1,x4,1)(by column up to x4) ...
From an image signal made up of a series of image signal components representing a radiation image, an abnormal pattern appearing as an approximately circular pattern in the radiation image is detected. A first finding device finds a prospective abnormal pattern appearing in the radiation image by ...
..,d15376} denote the set of all the code vector of weight 528528. Due to the above given weight distribution it follows that, if bi,bj∈Hbi,bj∈H are two distinct code vectors (i.e. i≠ji≠j), then the inner product between them defined over field of real ...
If you want so estimate the similarity of two vectors, you should use cosine-similarity or Manhatten/Euclidean distance. Spearman correlation is only used for the comparison to gold scores. Assume you have the pairs: x_1, y_1 x_2, y_2 ...
The MultiMatch metrics represent the scanpath as a set of vectors on a 2-D plane, as can be seen in Fig Fig. 12(B); each vector originates from the fixation point at time point t and points to the fixation point at time point t+1. Specifically, for two scanpaths P1={p11,…,p...
