Hi, I'm new to this forum and appreciate very much your help!! I need to get a table of Separate set of z2 values for each A value on following code
for A=0:0.01:0.8;
w=0.51;
k=1-exp(1-(G./(2*w)));
at=0.5*(4/pi);
F=37;
v=(13.7*(F.^(1/3)));
n=v/0.04;
for x=-pi/2:0.1:pi/2
C=A*sin(x)-w*cos(x);
if C<0.04
con=n*C;
else con=v;
end
if con<0
CON=0;
else CON=con;
z2=k.*at.*cos(x).*CON.*sin(x);
end
end
end

Value - G ?

You need to add an index of some sort to z2. For example:
counter=1;
for A=1:10
z2(counter,1)=A+23;
counter=counter+1;
end

A = (0:0.01:0.8)';
x = -pi/2:0.1:pi/2;
m = numel(A);
q = numel(x);
w=0.51;
G = 5; %%%%%%%%%%%!!!!!!!!!!!!!!!
k = 1-exp(1-(G./(2*w)));
at = 0.5*(4/pi);
F = 37;
v = (13.7*(F.^(1/3)));
n = v/0.04;
C = bsxfun(@minus,A*sin(x),w*cos(x));
con = n*C;
con(C >= .04) = v;
CON = con;
CON(con < 0) = 0;
z2 = k*at*bsxfun(@times,cos(x).*sin(x),CON);
or
A = (0:0.01:0.8)';
x = -pi/2:0.1:pi/2;
m = numel(A);
q = numel(x);
w=0.51;
G = 5; %%%%%%%%%%%!!!!!!!!!!!!!!!
k = 1-exp(1-(G./(2*w)));
at = 0.5*(4/pi);
F = 37;
v = (13.7*(F.^(1/3)));
n = v/0.04;
z2 = zeros(m,q);
for ii = 1:m % A=0:0.01:0.8;
for jj = 1:q %x=-pi/2:0.1:pi/2
ss = sin(x(jj));
cs = cos(x(jj));
C = A(ii)*ss - w*cs;
if C < 0.04
con = n*C;
else
con = v;
end
if con < 0
CON = 0;
else
CON = con;
end
z2(ii,jj) = k*at*cs*CON*ss;
end
end
