Respected sir i have attched one picture here , likethis picture i want to plot velocity(u) vs y plot
my formula for velocity profile is below whatever I have done in Matlab code I am writing below the formulae
U = 1./mu.*(t_o.*(y-delta)+4.*alpha.*sqrt(t_o.*t_e).*exp(- alpha./(2.*delta))+t_e.*alpha.*(1-exp(-y./alpha)))
% t_o=106;
t_e=156;
deltavals = 0.6 ;
alphavals = [-0.3,- 0.2 ,-0.1,0, 0.1,0.2,0.3 ];
yvals = 0.3:0.1:1;
[ alpha, y] = ndgrid( alphavals, yvals);
U = 1./mu.*(t_o.*(y-delta)+4.*alpha.*sqrt(t_o.*t_e).*exp(- alpha./(2.*delta))+t_e.*alpha.*(1-exp(-y./alpha)))
plot(y,U,'-r') end

OK, now, what is y?
t_o = 100;
t_e = 150
mu = 0.3
delta = 0.6
alpha = [0.1, 0.2, 0.3, 0.3, 0.4, -0.2, -0.5]
U = 1./mu.*(t_o.*(y-delta)+4.*alpha.*sqrt(t_o.*t_e).*exp(- alpha./(2.*delta))+t_e.*alpha.*(1-exp(-y./alpha)))
% t_o = 106;
t_e = 156;
deltavals = 0.6 ;
alphavals = [-0.3,- 0.2 ,-0.1,0, 0.1,0.2,0.3 ];
yvals = 0.3:0.1:1;
[ alpha, y] = ndgrid( alphavals, yvals);
U = 1./mu.*(t_o.*(y-delta)+4.*alpha.*sqrt(t_o.*t_e).*exp(- alpha./(2.*delta))+t_e.*alpha.*(1-exp(-y./alpha)))
plot(y,U,'-r')

sir due to problem in value i have non dimensionalise my final equation. i have attached the picture. in wquation one is valid from y =0 to y=0.3 and equation two is valid for y=0.3 to 1
I want to divide y in 0.01 interval
balue of delta 0.3
value of k=100
value of beta 0.01
please help me in wriying the programme and plotting
