How to Display Grid Lines with Specific Distance from One Another?

I want grid lines for a plot but MATLAB automatically define the number of grid lines. Is there any way to manually define the number of grid lines for a plot?

MATLAB put grid lines at every XTick or YTick position. You can set the axes XTick and YTick properties to change where the grid lines are to go.

For example:

   number_interior_x_gridlines = 7;
   ax = gca;
   XL = get(ax, 'XLim');
   xticks_at = linspace(XL(1), XL, number_interior_x_gridlines + 2);
   set(ax, 'XTick', xticks_at);

I get error while running your code.

I want 10 YTicks but only 2 grid lines

[Walter Roberson]

   number_interior_x_gridlines = 7;
   ax = gca;
   XL = get(ax, 'XLim');
   xticks_at = linspace(XL(1), XL(2), number_interior_x_gridlines + 2);
   set(ax, 'XTick', xticks_at);

"I want 10 YTicks but only 2 grid lines"

Then you will need to use line() to draw in the marks and text() to draw in the labels for the place you want the y ticks, using the YTicks setting to control the position of the grid lines. Or, alternately, you can have YTicks set where you want to get those drawn in automatically, and instead use line() to draw in the grid lines.
