Explanation / Answer

Solution:

min_all=mat(1,1);
pos_row_all=1;
pos_col_all=1;
for i=1:num_columns
min_each_col=mat(1,i);
row_pos=1;
for j=2:num_rows
if(min_each_col>mat(j,i))
min_each_col=mat(j,i);
row_pos=j;
end
end
fprintf('The minimum of column %d is %d and is in row %d ',i,min_each_col,row_pos);
if(min_each_col < min_all)
min_all=min_each_col;
pos_row_all=row_pos;
pos_col_all=i;
end
end
fprintf('The minimum of all the elements is %d ',min_all);
fprintf('The minimum is in row %d and column %d ',pos_row_all,pos_col_all);
