plot within a for loop and if statment
显示 更早的评论
i have this data of wells, where in the first column i need to sort out all the 1's in that coulmn and plot the x,y,z corresponding to that row where the 1 is. this is the code i have
b=sum(a==1);
hold on
for n=1:221
if a(n)==1
;
plot3(xTop(n),yTop(n),1:b:0'k-')
n=n+1;
end
end
the coulmn is 221 rows long and i have the vaiables for the x and y shown but the z needs to go from 1 to 0 and i cant get the legth right or something?? if this is confusing ask me more questions thank you

No for loop is needed.
% Find rows of "a" with 1's in the first column of "a".
rowsWith1s = a(:,1) == 1;
% Now extract them from the other arrays.
% (optional - you could do this inside plot3() if you want).
x = xTop(rowsWith1s);
y = yTop(rowsWith1s);
z = zTop(rowsWith1s);
% Now plot
plot3(x, y, z, 'bo-', 'LineWidth', 3);
% Make it fancy.
grid on;
xlabel('xTop', 'FontSize', 25);
ylabel('yTop', 'FontSize', 25);
% Enlarge figure to full screen.
set(gcf, 'Units', 'Normalized', 'OuterPosition', [0 0 1 1]);

I don't know what you mean. You gave us no information whatsoever on xTop, yTop, a, or z, so I'm hoping you can either figure it out yourself, or give us more info. I'll check tomorrow.
