Plot intersections on a question I was given.

Question 1.

Write z=peaks followed by lines of code in a script file, that plots row and column cross sections through z where the minimum and maximum values of z are.

I was given this question. I have got myself an answer, but I am not 100% sure if i've actually done what the question asked. I previously worked out the minimum value of z to be located at (27,12) and the maximum at (25,38). I then proceeded to do this:

z = peaks
hold on
plot(z(:,27));
plot(z(12,:));
plot(z(:,25));
plot(z(38,:));
hold off

This created me a 4 graphs which to my knowledge are the intersects of z.

Any help would be great, many thanks.

Hi,

As per my understanding,

Z= peaks returns a 49*49 double array,

Using the minimum and maximum values provided, you have created a 2-D plot from the Z array.

hold on
plot(z(:,27));
plot(z(12,:));
plot(z(:,25));
plot(z(38,:));
hold off

From the 2-D plot you can obtain the intersects of Z.
