datetick seems a good place to start. Otherwise you can see if the xtickformat function suits your need.

y=gyields(:,1)
startDate = datenum('01-1990')
endDate = datenum('01-2019');
xData = linspace(startDate,endDate,360)
plot(xData,y);
ax = gca;
ax.XTick = xData;
datetick('x','yyyy')
these are my code,but i have this error
"Error using matlab.graphics.axis.decorator.DatetimeRuler/validateTicks
Value must be a vector of increasing datetime values.
Error in matlab.graphics.axis.decorator.DatetimeRuler/setTicksDelegate"

The datenum values that are generated by your code didn't match what I expected, so I edited it a bit. The code below runs without errors or warnings.
S=load('example.mat');y=S.y;
startDate = datenum('01-01-1990');
endDate = datenum('01-01-2019');
xData = linspace(startDate,endDate,360);
plot(xData,y);
set(gca,'XTick',xData);
datetick('x','yyyy')
