delete value in matrix with condition

Let's say, I have 2 matrix:

A=[1 9 5 6;2 1 4 5;3 4 3 5];%matrix A
dist_A=[0.1 0.6 0.4 0.5; 0.5 0.1 0.2 0.3; 0.2 0.9 0.7 0.4];%matrix dist_A
condition=0.5;%this is value to check condition

A=[1 9 5 6

2 1 4 5

3 4 3 5];

dist_A=[0.1 0.6 0.4 0.5

0.5 0.1 0.2 0.3

0.2 0.9 0.7 0.4];

My question is:

1/ I want to delete values in matrix "dist_A" that satisfy condition: If that value <= condition(0.5)

I hope the result is:

result_dist_A=[0.1  0.4 ;  0.1  0.2  0.3; 0.2  0.4];

2/ Delete the value in matrix A having the same index of the deleted value in matrix "dist_A"

I hope the result is:

result_A=[1  5 ; 1  4  5; 3  5];

[KSSV]

result_A=[1  5 ; 1  4  5; 3  5];

The above will trhow an error. I would suggest you to replace the unwanted value with NaN...so that dimensions remain apt and no error pops out.

R=arrayfun(@(x)A(x,dist_A(x,:)<0.5),1:size(dist_A,1),'un',0);
R{:}

Gives:

ans =

     1     5

ans =

     1     4     5

ans =

     3     5
