Try this:

a = -7.28135827387422e-05
aString = num2str(a)
decimalLocation = strfind(aString, '.')
aString = [aString(1:decimalLocation-1), aString(decimalLocation+1), '.', aString(decimalLocation+1:decimalLocation+3)]
aNumber = str2double(aString)

b = 1.87033878860991e-35
bString = num2str(b)
decimalLocation = strfind(bString, '.')
bString = [bString(1:decimalLocation-1), bString(decimalLocation+1), '.', bString(decimalLocation+1:decimalLocation+3)]
bNumber = str2double(bString)
