I have 2 arrays of data that I have calculated ( X1 and Y1). I plot them and can see the min and the max points. I need these points. I use the command:

P:=ExtremePoints(X1, Y1);

And it gives me:

P:=ExtremePoints(X1, [4, 2,3,1,5,0.3,4]);

I expected that P will be an array and when I used the command:

N:=ArrayNumElems(P);

It will give me the total number of the min and max, but it gives me a mistake.

I will...

Hi,

I need some help, I have tried some variants of finding of min of an array but it did not work.

I have declared an array (T:=array(1..10), then using a cycle to calculate the values of this array. I can read this array and plot the data and see the min and max values(for example: (1,2,0,3,4,5,6,3 ,-1,5)), but I can not automatically calculate  the min and to find that this is exactly T[9].

Is there special function that I can use for this or...

For i=1 I need to calculate the variables  t12[i], t13[i] ... and t18[i], then to  calculate Cn(i,n)=F(t12[i], t13[i] ... and t18[i]) as n increase from 1 to 15 and then to increase i and calculate all these  variabels another time and this will continue to i=5.

How to make the nested loop for this example?

Thank you ,

Tanya
