Hi, how to make a condition, if grid minor; I am trying to do:

 if grid==minor
     a=1
  else
     a=0
  end

That may be relatively old (pre-R2014b) syntax.

See Display Major and Minor Grid Lines.

MATLAB: XGrid and XTick with different space

I ran your code and see your problem: the high frequency grid lines make it impossible to read the ticks and hard to see the plot.

You should be able to solve this issue using "Minor Ticks", which is exactly what you are looking for--a smaller tick that has no label, but will allow you to manipulate the size of the grid to your desire. Keep in mind that this functionality was introduced in MATLAB R2015b.

Minor ticks are associated with each axis of the axes. So you can specify a range of minor ticks for the XAxis and the YAxis. After you specify your tick values, make sure you write `grid minor` to make the grid follow the minor ticks!

You can find more information on minor ticks in the following documentation page: https://www.mathworks.com/help/matlab/ref/numericruler-properties.html

Here is an example based on your attached code:

    figure
    plot( [-1 1] , [ -1 1]  )
    set(gca,'Xtick',-1 : .25 : 1); %sets the numbered ticks .25 apart
    set(gca,'Ytick',-1 : .25 :1); %same as above
    ax = gca; %get the current axes
    ax.XAxis.MinorTickValuesMode = 'manual'; %say you are setting the values yourself
    ax.XAxis.MinorTickValues = -1:.025:1; %specify tick spacing to be .025 for minor ticks
    ax.XAxis.MinorTick = 'on'; %set the minor ticks to display!
    ax.YAxis.MinorTickValuesMode = 'manual';
    ax.YAxis.MinorTickValues = -1:.025:1;
    ax.YAxis.MinorTick = 'on';
    grid minor; %set the grid to follow minor ticks.

Hope this helps!
