Set the tick values and the limits, not tick labels. Tick labels just write the label values on the tick marks that have been otherwise set by the auto-scaling routines; they have nothing to do with how many or what the actual values are.
set(gca,'XLim',[103.6 104],'XTick',[103.6:0.10:104])
set(gca,'XLim',[1.25 1.50],'YTick',[1.25:0.05:1.50])
NB:
You don't show actual data; you've written the 'yticklabel' in descending order; that may not be the same as the ticks themselves unless you've previously done
set(gca,'ydir','reverse')
