MATLAB: Matrix Multiplication column and vector

MATLABmatrix multiplicationStatistics and Machine Learning Toolbox

Hi,

I am trying to solve this problem:

A is 1 column of 100k results; B is a vector of 10 weights; I need a matrix of 10 columns and 100k rows:

[(result line 1)*W1 (result line 1)*W2 (result line 2)*W1 (result line 2)*W2 …

Thank you very much,

A is 1 column of 100k results; W is a vector of 10 weights;

A(:)*W(:).'

Let

Yourvector = randi(1000,100,1);
out = reshape(Yourvector,10,[]);

Columns in out - your vectors.

Transpose and use ismember(A,B,'rows')

A=A';370x3
B=B';1x3
x=find(ismember(A,B,'rows'));%will give you the column numbers of A that match B
