Can you label multiple figures with the same x & y labels with just one line of code?

I have some code that looks like this:

 if figs==4
      figure
      plot(X(:,1:7))
      xlabel('Data point number')
      ylabel('Amplitude')
      figure
      plot(X(:,8:14))
      xlabel('Data point number')
      ylabel('Amplitude')
      figure
      plot(X(:,15:22))
      xlabel('Data point number')
      ylabel('Amplitude')
      figure
      plot(X(:,23:30))
      xlabel('Data point number')
      ylabel('Amplitude')
  end

Is there some way I can label the x & y labels for all the figures the same thing, with one line of code, instead of having to write the labels out each time I have a figure.

Here is the original question, for when Mary overwrites it with gibberish:

I have some code that looks like this:

 if figs==4
      figure
      plot(X(:,1:7))
      xlabel('Data point number')
      ylabel('Amplitude')
      figure
      plot(X(:,8:14))
      xlabel('Data point number')
      ylabel('Amplitude')
      figure
      plot(X(:,15:22))
      xlabel('Data point number')
      ylabel('Amplitude')
      figure
      plot(X(:,23:30))
      xlabel('Data point number')
      ylabel('Amplitude')
  end

Is there some way I can label the x & y labels for all the figures the same thing, with one line of code, instead of having to write the labels out each time I have a figure.

See if this does what you want:

axlbl = @(h) [xlabel(h, 'Data point number'); ylabel(h, 'Amplitude')];
figure
plot(rand(1,10), rand(1,10))
axlbl(gca);
figure
plot(rand(1,20), rand(1,20))
axlbl(gca);

The gca function ‘gets’ the ‘current axis’ handle, that is then passed to the function and used by the xlabel and ylabel functions to put the labels on the correct axes.
