Sorry for late reply
In that 11x11 matrix, I use only 66 values (nonzero part).
these values are multiplied with 66x812 sensitivity matrix and get 812 pixel values.
Then these values are placed on a 32x32 frame, in a circular shape.
In every for ex. 50 msec one frame is shown and the flow in a pipe is monitored.
I really appreciate your help.
Thank you
