roblem A:Use the Matlab function polyfit.m to fit an exponential equation of the form:y=aebx, tothe datax0.61.02.33.14.45.87.2y3.62.52.21.51.11.30.9Answer:a=3:23 andb=0:188.
Problem B:The river sediment concentration is often described by the Rouse concentration equation:c=K1ξ1z(28)wherec=sediment concentration at a relative distanceξ, and(K;z) =fitting parameters. Fit theabove concentration equation with the concentration data in Problem 2, and find the values of(K;z).Hint: Transform Eq. (28) intolnc=zln1ξ1+lnK(29)and fit the data in terms of lncversus ln(1=ξ1).
