I have an increasing exponential function that I need to apply first half of the array and a decreasing exponentail function that needs to be apply to the last half of the array. The increasing exponential function is:
a = 0.879;
b = -0.01986;
y = a*exp(b*x);
and the decreasing exponential funciton is:
a2 = 0.06784;
b2 = 0.01986;
y2 = a2*exp(b2*x);
Is it possible to concatenate this two equations into one?
I'm multiplying these two equations to an array of 128x4224 with the following command:
dataCorrected = bsxfun(@times, dataCorrected, [y y2]);
And I would like y to be multiplied from row 1-2112 and y2 to be multipled from row 2113-4224.

Yes, it is possible. Let dataCorrected be your 128*4224 array and y, y2 be 1*2112 vectors.
iwant = dataCorrected.*[y y2] ; % element by element multiplication

IT depends on how you want. And it depends on the values of x.
