Hello all, I'm keep having error when I tried to put title on my plot. The error message said "Index exceeds matrix dimensions." Here's my code, so please let me know why I got this message. Thanks!
figure
title('2')
h = plot(dataCenter(:,1),dataCenter(:,2),'Color','b')

Can you tell us about the dimensions of dataCenter? or upload it ? and for the title to be added to the graph, please use the command after the plot command

Thanks kowshik Thopalli!! dataCenter is 10*2 matrix.
dataCenter =
0 0.0200
10.0000 0.0300
20.0000 0.0350
30.0000 0.0700
40.0000 0.0900
50.0000 0.0950
60.0000 0.0950
70.0000 0.1000

The error message is clear: An indexing operation in this line exceeds the defined array sizes:
h = plot(dataCenter(:,1),dataCenter(:,2),'Color','b')
Either dataCenter has 1 column only, or you have redefined plot by an array and the inputs are interpreted as indices. You can check both by using the debugger. Type this in the command window:
dbstop if error
Now run the code again until it stops at the problem. Now examine, what's going on:
size(dataCenter)
which plot -all
