Setting Tic Marks

[Joe Koski]

I'm trying to manually set tic marks on a plot. According to "help tics,"
the tics function has the form:

  tics(axis,[pos1,pos2,...],['lab1';'lab2';...])

Rather than typing a long array of pos1,pos2,pos3,..., I would prefer to
define a vector, and then pass it to tics, but I can't seem to find the
correct format. What I have tried is:

figure(ifig);
clg;
legend('off');
axis('auto');
title([in_file," - Power Spectrum - Welch"]);
xlabel("Frequency, Hz");
ylabel("Signal Amplitude, dB");
Pxt=10*log10(abs(Px'));
axis([0,20000]);
tic_array = int2str([0:1000:20000])
tics(x,tic_array);
grid on;
plot(w,Pxt);

where tic_array is a character string with the correct values, but with
space, not comma, delimiters. Without the commas, I get an error message.

Is there a simple way to convert a vector into something usable by "tics?"

Thanks,

Joe
