MATLAB: How to change Elements in Matrix per row depending on their size in reference to a particular Element (without loop)

#refbiggerchange elementschange sizeefficientmatrix manipulationsmallerwithout loop.

I've Data (in the real case much bigger) like this: A =
     0     3     4     5     2     3     1
     2     4     6     2     1     6     8
     1     1     1     3     2     1     8
     4     4     3     3     1     0     0
     2     3     2     2     1     9     0
Not I want to change elements in different rows if they are bigger than a particular number: For example in Row 1,3,4 there should not be an Element bigger then 3 and in Row 2,5 there should not be an Element larger then 2.
So the Result should look like: A =
     0     3     3     3     2     3     1
     2     2     2     2     1     2     2
     1     1     1     3     2     1     3
     3     3     3     3     1     0     0
     2     2     2     2     1     2     0
I tried to solve the Problem like this but it doesnt work:
A(A([1 3 4],:)>=3)=3
A(A([2 5],:)>=2)=2
Does someone have a good solution or does anyone know where my mistake is?

Best Answer

B=A([ 1 3 4],:);
B(B>3)=3
A([1 3 4],:)=B
B=A([ 2 5],:);
B(B>2)=2
A([2 5],:)=B
