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]);
