Vector limiting value
Vector limiting value
(OP)
Guys Im wondering if you could help me a bit.
If you could open the file attached.
I defined a vector wich goes from 0-1000mm with delta=1mm.
Problem is that I have a formula in my sheet that should use for x, as a final value, infinity.
I tried enlarging the limiting value for x, wich is 1000mm to some BIG number but every time I get above 100000, Mathcad craches.
Can this be due to small amount of memory (4GB)?
Is there any chance that this vector can also have the infinity as the last value?
Thank you

RE: Vector limiting value
In any case, there is no problem with defining y.end up to about 10E7. But the notion that one needs 1-mm resolution over a 10km does not make sense.

RE: Vector limiting value
Is this interpreted as infinity in Mathcad or not?
Do you have any problems with Mathcad crashing when operating with so large values?

How can you possibly expect a plausible answer without any context?

RE: Vector limiting value
I dont Know if you have downloaded my project that Ive uploaded last month, when you said that it was an "homework" attempt, but if you have you can basicly see that there is an value called x at the begining wich you can set from 0mm to infinity.
The whole project has been set up with vectors now and it works.
x is defined as a vector in my previous attach
The only problem remaninig is how to account for a value - infinity.
Becasue when x=infinty the 2 M values become 0 (zero).
I could use as you mentioned an large value for like 10E7 but that doesnt give 0 to my 2 M values.
They are very very close to it, something like 0,05
Maybe to use the rounding function in these situation wich would round those small values to ZERO.
Again, did you experienced any troubles when using so BIG ranges?
Did Mathcad crashed?

Did Mathcad crashed?"
Your question was answered in my first post, and no, Mathcad did not crash.

RE: Vector limiting value
It might my wise to enlarge the increment value, but in that way I might get in situation where Im loosing some of the important points (values).
Is there any way that besides defining a range of values (wich almost always follow a sequence) you can define Extra few values that are of great importance (but are unfortunatly going to be skipped using a sequence)
@struct
Im contoling the position of the neutal axis of a cross section. SO when n.a. is at infinity you have a section in pure tennsion or compression. Moments are ZERO! Important value wich I dont Know how to include.
RE: Vector limiting value
Again, where would you actually need an infinite number of millimeters? You have nothing in your original problem that would have that; if you do, then you need to figure out how to get around that.

Can you explain your solution/advice regarding my previous post where I said that infinity is an important vlaue that should be an end part of a sequence.
Thank you.

Or maybe just define few values that dont follow any particular sequence?

RE: Vector limiting value
You can set the zero threshold with Format|Result|Tolerance|Zero Threshold. If set at 15, then numbers smaller than 1E-15 show up as zero.
