MATLAB: Linear Combination of 3 matrices.

linear combination

How do you compute the linear combination of 3 (1×3) matrices.

Best Answer

There are an infinite number of linear combinations of matrices: you cannot compute them all.

Is it possible that the question you are dealing with has to do with finding the point that is at the intersection of linear combinations of three vectors?

[M(:) N(:)]\C(:)   produces  [a;b]

This assumes that M and N are not proportional to each other, otherwise there are an infinite number of solutions.

MATLAB: Avoid loops with matrices.

You can use accumarray to get the same output, although the for loop is still about twice as fast as accumarray (for that data). Which method is fastest may depend on the data size.

>> accumarray([a',b'], q, [5,5], @(x){x})
ans = 
     []    [2x1 double]              []              []              []
    [8]              []    [2x1 double]              []              []
     []    [         7]              []    [2x1 double]              []
     []              []    [         6]              []    [2x1 double]
     []              []              []    [2x1 double]              []
