I realise that it's easy enough to plot a simple graph of x and y data which have already been calculated in an array, eg :
x=-1:0.01:1;
y=sqrt(1-(x.^2));
plot(x,y)
will give me a chart of my simple curve.
However, if I change the increment from 0.01 to 1E-7 the calculations are fast enough but the plot takes quite a while to appear.
I'd like to plot the x,y position data as they're calculated rather than waiting until the end of all the calculations.
I tried this :
x=-1;
while(x<1)
y=sqrt(1-(x^2));
plot(x,y)
hold on
x=x+0.01
end
but it only plots my last point rather than plotting all the points on the curve as it calculated them.
I'm guessing that Matlab only undertakes a plot once calculation loops are completed (?).
It might be that I'm being dumb or maybe that plotting a curve point by point as they are calculated just isn't supported?
I realise I can just use the first method, keep all my data pairs and plot at the end of all calculations. This will, in practice, probably result in me spending a lot of cumulative unnecessary time sitting in front of my computer!
Can anyone offer a solution to help with my preferred approach of plotting the data 'point by point' as they are calculated (or confirm that Matlab just doesn't do this sort of thing) please ?
