Suppose I have an array that is a large m x n matrix. For a value y, if the numbers in this matrix are less than y, then i want to replace those values with 0, otherwise they are 1. how to compute this? I have written a rudimentary code, but i need help.
df = xlsread("Book1.xlsx");
for i = 1:448 %448 = number of columns
x = df(:,i)
if x < 40
x = 0
else
x = 1
i = i + 1
end
end
