Replace values in each column of a matrix which lie below a threshold

Hi all,

Lets say I have the following matrix:

a =

    0.9952    0.6999    0.2940
    0.0034    0.2553    0.5776
    0.3167    0.3135    0.4261

I would like to replace with zero the numbers in the first, second and thrid column that are less than 0.5, 0.3 and 0.8 respectivelly, so the result would be:

a_new =

    0.9952    0.6999    0.0000
    0.0000    0.0000    0.0000
    0.0000    0.3135    0.0000

To do this, I try something like this a(a<[0.5 0.3 0.8],:)=0, however this doesn't work... Ideally I would like to avoid a for loop, so are there any other ways of accomplishing the above?

Thanks for your help in advance

a(a < [0.5 0.3 0.8]) = 0
