I have a matrix of size 3*4*4*9862
3=lat
4=lon
4=pressure
9862=number of days
I want to multiply 9.80665 with the values of this matrix if I multiply it like
k=matrix
k1=k*9.80665
or any other way

Let k be your 4 dimensional matrix. Use
k1=9.80665*k;

If this formula is applicable for 9862 days?Or only for one day?

It multiples every single value (element) in the whole matrix by that number. If you want to multiply only some days, then you'll have to index those. Like to multiply only elements with day indexes between 1000 and 2000, do this
k1 = 9.80665 * matrix(:, :, :, 1000:2000);
