Try this
load('germany.mat');
dates = datetime(char(germanyields.Maturity), 'InputFormat', 'yyyy-MM');
surf(gmaturities, dates, gyields)
xlabel('gmaturities');
ylabel('Date');

thank you so much,its exactly that i wanted,but i run in the metlab and the output is like this(the place of axis x and y replaced),i rote it but it was noy like yours.
so sorry that my questions are so basic.
Yes, I rotated it manually. You can try the following code.
load('germany.mat');
ax = axes();
dates = datetime(char(germanyields.Maturity), 'InputFormat', 'yyyy-MM');
surf(gmaturities, dates, gyields)
xlabel('gmaturities');
ylabel('Date');
ax.YDir = 'reverse';
Are you looking for some other modification?
