I'm taking an introductory matlab course and am working on quite a simple assignment, where I plot an exponential function (of remanining radioactive nucleides) against time and create a matrix containing the values for the first 10 days. C

The starting value for the exponential function is 10 000. The issue now is that matlab expresses both the days and the remaining nucleides against time. I would like it to instead display the values as they are (such as 0, 10 and 8300). How do I do that?

Here

x = log(2)/3.8;

N0 = 10000;

t = 0:1:10;

N = N0 * exp(-t*x);

M = [t ; N]

And here's my output:

M =

1.0e+04 *

0 0.0001 0.0002 0.0003 0.0004 0.0005 0.0006 0.0007 0.0008 0.0009 0.0010

1.0000 0.8333 0.6943 0.5786 0.4821 0.4017 0.3347 0.2789 0.2324 0.1937 0.1614

Is there a way to change the way it's expressed?
