best way to get a vector from sparse matrix
- by niko
Hi,
I have a m x n matrix where each row consists of zeros and same values for each row.
an example would be:
M = -0.6 1.8 -2.3 0 0 0; 0 0 0 3.4 -3.8 -4.3; -0.6 0 0 3.4 0 0
In this example the first column consists of 0s and -0.6, second 0 and 1.8, third -2.3 and so on.
In such case I would like to reduce m to 1 (get a vector from a given matrix) so in this example a vector would be (-0.6 1.8 -2.3 3.4 -3.8 -4.3)
Does anyone know what is the best way to get a vector from such matrix?
Thank you!
