help me with this for loop please
显示 更早的评论
x = -10:0.1:10;
y = 0:0.005:1;
minNmax1 = 0:.005:1;
upper_1 = 0:.005:1;
y2 = 0:.005:1;
f1 = trapmf(x,[-2 0 0 2].');
minNmax1 = zeros(length(x), 2);
for k = 1 :length(y)
minNmax1(k,:) = [min(x),max(x)];
end
I'm trying to get [min(x),max(x)] for 201 values of y but this will only give me 1 answer [-10 10] which i assume is the first iteration?
help!

Sorry it is not clear what you would like in your variable. min(x) and max(x) are both constants, it will fill your 201x2 matrix with -10 in the first column and 10 in the second. Could you please explain more what you would like to achieve?
I cannot understand your notation. What does "@ y = 0.01 min(x), max(x)" mean? There is no "y" in this expression on the right hand side. What does the "y=0.01" part mean? Which y-values do you want to check and do you think that any y-value is exactly 0.01?
Perhaps you want "f1" to appear anywhere?

How does f1 depend on y?

Check my picture please, I need to find those starred points for all the red lines (201 of them)

will min(x) always be the same number as x is not changing? you can use repmat(min(x), 201,1)) if that is the case
