sum of exponentials
Posted:

I have a matrix whose data are interrupted by sequences of zeros. I need every time that there's a zero value to substitute it with a sum of exponentials using the previous data, eg: x=[x1 x2 x3 0 0 0 x7 0 0] When i find the first zero in the element x4 I want: x4=(x3*e^(1)+x2*e^(2)+x1*e^(3))/(e^(1)+e^(2)+e^(3)); However, when I find the second zero value I need to calculate the same expression but without using the previous recalculated values. That is, x4=x5=x6 and for x8 I will use only the values in x7,x3,x2,x1 and then x8=x9 etc And all this for a 180000length data. Any ideas on how to do this? Thanks in advance
