Hi everyone,
I just started using EIGEN and I have this code below. The purpose is to read (80,000 x 80,000) a matrix from a txt file, generate a inverse from a pseudoinverse method and write the result in a output file. I found 2 methods and I'm trying to use it ... Any comments or suggestions will be appreciate. Thanks in advance! Raphael

Hi,
for efficiency reason, I'd recommend to use a QR decomposition though the algorithm might be a little more complex. |

Hi GGAEL,
Thanks for your reply. I will check this QR method. Have a good day, Rafael |

Hi GGAEL,
I'm trying to call the function pseudoinverse() in this case, testing a small matrix, but I'm getting confused:
What is the correct way to call this function? I'm also researching on the QR as you suggested. Thanks, Ricardo |
