Hello
I have a lot values (equal to -999.25) in my data columns. I want that matlab read these values (-999.25) as zero when ever I load or run my data on MATLAB. How can I fix this problem? Please help

a = [ 1 2 3 -999.25 -999.25 4 5]
a(a == -999.25) = 0

DTP = clew(DTP);
DRZ = clew(DRZ) ;
function A = clew(A)
A(A==-999.25) = nan;
So you would have 10 lines of assignment, one for each variable.
Yes it is possible to do it in fewer lines with more confusing code.
But better would have been to store all of the arrays in the same variable, such as a multidimensional array or cell array or struct. Any of those could have all fields processed easily, like
Dats = structfun(@clew, Dats, 'uniform', 0)
