How to not draw some points of an interval( hmax and hmin )

I have this function but i have to finish it. I have to say to matlab to not draw the points of the graph between hmax and hmin Can someone help me???

h = max(y); hmax = (percT/100)*h; hmin = (percB)/100*h;

for i=1:size(y,1) if y(i)> hmax y(i) = hmax; else if y(i)< hmin y(i) = hmin;

        else.....how i have to finish???

Many thanks in advance!!!

Dear Antonella, Can you share complete code because information about variables like "y", "percT", "percB" and also which value you want to plot?

[Antonella]

percT is 60 an percB is 30. the variable y rapresents the high of the graph (the graph is about a hand-written word). So i have to remove the middle part of this graph(word) so every point between 30-60% of the total high. Hope this is clearer! Many thanks in advance!

You can use logical indexing to remove any values greater than and less than the desired bounds.

% Defining some arbitrary data
x = 0:0.05:2*pi;
y = sin(x);

% Defining some arbitrary bounds
hmax =  0.5;
hmin = -0.5;

y_bounded = y;
% Using logical indexing to replace all values > hmax with NaN
% When plotting, MATLAB ignores values that are defined as NaN
y_bounded(y_bounded > hmax) = NaN;
y_bounded(y_bounded < hmin) = NaN;

% Plot Results
plot(x,y,x,y_bounded,'o');
grid on;
legend('Orignal Data','Bounded Data');

Hope this helps!

thanks really much for the answer! I'll try and check if it's work! Anyway i have to use if, else if ecc...how i can translate what you wrote me in this way? is there the possibility to do this or not? Really many thanks ;)
