I have equation CL = 2*(sin(alpha))^2 * cos(alpha)
and value of CL = -0.525
I need value of alpha using trail and error running for loop in MATLAB but not getting, Please help me with possible soution

If your goal is simply to get smooth curves through those points, you can just do spline interpolation:
x1 = [3.34, 3.93, 3.65, 2.50, 1];
x2 = [0.19, 0.36, 0.64, 0.84, 1];
y = [0.10, 0.20, 0.40, 0.60, 1];
yf=linspace(0.1,1,50);
x1f=interp1(y,x1,yf,'spline');
x2f=interp1(y,x2,yf,'spline');
% draw the original coarse curves
plot(y,x1,':'); hold on; grid on
plot(y,x2,':');
% draw the smoothed curves
plot(yf,x1f);
plot(yf,x2f);
Feel free to swap axes if you want the plot facing the other way
If you find the endpoint behavior of 'spline' to be too outrageous, try 'pchip' or 'makima':
