I use the bvp4c function in Matlab software to find dual solutions for the wall shear stress parameter ( f''(0) ) in the equation of " f'''+ff''=0, f(0)=m, f'(0)=L, f'(infinity)=1 ".

there is a region of unique solutions for L> 0 , dual solutions for Lc < L < 0 and no solutions for L < Lc. What way do you recommend to find the dual solutions for f''(0) by bvp4c function?
