Efficiently setting lower axis limit

I would like to set the lower axis limit and leave the upper limit at the auto value (rather than specifcy the upper limit myself). At the moment I do this to set the lower limit at zero:

xlim_curr = get(gca,'xlim'); 
xlim_curr(1) = 0;
set(gca,'xlim',xlim_curr)

Is it possible to do this with a single line of code?

Thanks

One line:

set(gca, 'XLim', [0, get(gca, 'XLim') * [0; 1]])

Or without assuming that the lower limit is 0:

set(gca, 'XLim', get(gca, 'XLim') .* [0, 1] + [lowLimit, 0])

But your three lines are easier to read and faster to debug.

I use the xlim function. When called with no arguments, it returns the current limits:

xlim([0, max(xlim)])

You could do it in two lines:

xlim_curr = get(gca,'xlim');
set(gca, 'xlim', [0 xlim_curr(2)]);

I've tried to do exactly this before (fix one axis limit and allow the other to auto-scale), and could not figure out a better way.

From the documentation of r2018b:

'Create a surface plot and show only y values greater than 0. Specify the minimum y-axis limit as 0 and let MATLAB choose the maximum limit.'

[X,Y,Z] = peaks;
surf(X,Y,Z)
ylim([0 inf])
