How to index variables in two combined function for overwriting data

4 Ansichten (letzte 30 Tage)
Hi everyone! Kindly ask about help in function. Could you please help which varibles should be indexed. If I will use X0, Y0, Z0 as a first point and calculate Xr, Yr, Zr, Theta, Phi with help of two function. And then Xr, Yr, Zr, ThetaBar, PhiBar will be overwrited for X0,Y0,Z0 and new Xr, Yr, Zr will be calculated, and so on. Thank you in advance
X0 = 1.5;
Y0 = 1.5;
Z0 = 3.0;
Theta0 = 30;
Phi0 = 90;
K = 4;
X(ii) = [X0 zeros(1,K)];
Y(ii) = [Y0 zeros(1,K)];
Z(ii) = [Z0 zeros(1,K)];
Theta(ii) = [Theta0 zeros(1,K)];
Phi(ii) = [Phi0 zeros(1,K)];
for ii = 1:K
[XBar, YBar, ZBar, ThetaBar, PhiBar] = reflection5(X0(ii), Y0(ii), Z0(ii), Theta0(ii), Phi0(ii));
[p, Xr(ii), Yr(ii), Zr(ii), ThetaBar, PhiBar, tempPlane] = planeLocation5(XBar(ii), YBar(ii), ZBar(ii), ThetaBar(ii), PhiBar(ii));
X(ii+1) = Xr;
Y(ii+1) = Yr;
Z(ii+1) = Zr;
Theta(ii+1) = ThetaBar;
Phi(ii+1) = PhiBar;
end
Best regards, Aknur

With some bold guessing:
X0 = 1.5;
Y0 = 1.5;
Z0 = 3.0;
Theta0 = 30;
Phi0 = 90;
K = 4;
X = [X0 zeros(1,K)];
Y = [Y0 zeros(1,K)];
Z = [Z0 zeros(1,K)];
Theta = [Theta0 zeros(1,K)];
Phi = [Phi0 zeros(1,K)];
for ii = 1:K
[XBar, YBar, ZBar, ThetaBar, PhiBar] = reflection5(X(ii), Y(ii), Z(ii), Theta(ii), Phi(ii));
[p, Xr, Yr, Zr, ThetaBar, PhiBar, tempPlane] = planeLocation5(XBar, YBar, ZBar, ThetaBar, PhiBar);
X(ii+1) = Xr;
Y(ii+1) = Yr;
Z(ii+1) = Zr;
Theta(ii+1) = ThetaBar;
Phi(ii+1) = PhiBar;
end

@Aknur: "But it does not take result of Xr, Yr, Zr instead of X0, Y0, Z0 for the next iteration." - As far as I can see, it does:
X = [X0 zeros(1,K)];
Y = [Y0 zeros(1,K)];
Z = [Z0 zeros(1,K)];
Theta = [Theta0 zeros(1,K)];
Phi = [Phi0 zeros(1,K)];
% for ii = 1:K First iteration:
ii = 1
% Then X(ii) = X0
% XBar is calculated and used to get Xr. Then:
X(ii+1) = Xr % This is X(2)
% Next iteration:
ii = 2
% Now X(ii) = X(2), which is Xr of the previous iteration.
This sounds like what you are asking for. If not, modify the corresponding index.

Hi @Jan yes, that is it. Thank you sooo much. It works perfect!| I was just mixed with 0 value and ii
