What is pass a 2D array to a functions?
Modify the selection sort function developed in this chapter so that it accepts a second optional argument, which may be either 'up' or 'down'. If the argu-ment is 'up', sort the data in ascending order. If the argument is 'down', sort the data in descending order. If the argument is missing, the default case is to sort the data in ascending order. (Be sure to handle the case of invalid arguments, and be sure to include the proper help information in your function.)
Here is the given function which need to be mofified:
function out = ssort(a)
nvals = length(a);
iptr = ii;
for jj = ii+1:nvals
if a(jj) < a(iptr)
iptr = jj;
end
end
if ii ~= iptr
temp = a(ii);
a(ii) = a(iptr);
a(iptr) = temp;
end
end
out = a;
# Write a function to copy one array to another by using pointers. Comment/Discussion on the obtained results and discrepancies (if any).
