removing the array elements

%testing the elimation of the elements outside the boundary%

np=22;

L=10;

x=linspace(0,L,np);

%position(:,1)=x;

for i=1:np

if x(i) > 5

x(i) = [ ];

end

end

hello, i want to eliminate the value of x greater than 5 , i s not able yo do so. it says index array exceeds array bounds

#No Need of loop, efficient code.

np=22;
L=10;
x=linspace(0,L,np);
idx=find(x>5);
x(idx)=[]

If loop is needed, you can understand the issue from the comment section.

[KALYAN ACHARJYA]

using for loop you can undestand the issue from the following example

np=22;
L=10;
x=linspace(0,L,np)
for i=1:length(x)
if x(i)>5
    x(i)=NaN
end
end

As @Star explained if you delete the element, the array length reduce, therefore it reflects the error

index array exceeds array bounds
