interpolate

Hi all, I hope someone may be able to point me in the right direction. I have plotted data points from a pdf and created a spreadsheet, from this spreadsheet i have created an scatter graph of the pdf. The torque values are determined by the speed of an electric brake and the current output...

Hey there I'm currently working on results a sensor gave me via the data streamer. This gives out Coolums D and E which is the time and the data of the sensor. Later on I will have 2 sensors which I want to compare. So I will have 2 sets of 2 collums each. The comparison is simply the result of...

Hi Guys, I've recorded engine data and two of the variables recorded were engine speed and coolant temperature. To determine friction torque, the table below needs to be used: <colgroup><col><col><col span="16"></colgroup><tbody> Engine Speed 400 800 1000 1100 1200 1300 1400 1500 1600 1800...

Right I have numbers from -90 to 90 by 1 with values and I need to interpolate numbers from -90 to 90 by 0.1. I need my formula to skip 10 cells then increase to use new numbers to interpolate, so for numbers between -90 and -89 it uses those values then -89 to -88 for the next 10 interpolated...

Hi, I have a dataset with a variable versus depth (see below example). I want to calculate a weighted average of a calculated subset of these data, for example, the weighted average from 3.2 to, say, 8.7. I know how to calculate the weighted average of the full dataset, but not a subset, which...

Hello everyone, I am attempting to interpolate weather data that I have acquired but doing in by hand is not ideal. I was hoping that someone proficient in writing macros could help. I have attached an image showing what I am trying to achieve. The yellow cells are the cells with my...

Hello, I have this table which I wrote by getting values from a graph (included in the image below). I am able to get the exact values as far as they match the values in X and Y axis using the INDEX and MATCH functions. What I am trying to achieve is to get interpolated values for the X...

OK, I am trying to interpolate and perform calculations from a table based on multiple variables at the same time. I have sort of figured out part using nested if statements, but it is getting ugly fast, so I am hoping for some help. What I have is a table defining how to find the value for Ca...

Hi, I have a list with data for vehicles' speed vs grade%. I'm currently using this formula but is suspecting that this is not very accurate and gives errors: =FORECAST(I10,OFFSET(speed_loaded1,MATCH(I10,grade_loaded1,1)+1,0,2),OFFSET(grade_loaded1,MATCH(I10,grade_loaded1,1)+1,0,2)) Can...

Hi, I have an interpolation function that I have tried to write in VBA. The results of the function are correct when the given X value (in my case sigma) is equal to or outside the bounds of the highest or lowest sigma. But when the given X value or sigma for which I'm trying to interpolate...

Hello. I am trying to establish my electricity consumption for any period throughout the year, obviously summer months or quarters will be less than winter months or quarters. I have meter readings from odd points in the year as follows: 28/05/2010 9069 12/06/2010 9339 17/06/2010 9455...

G'day, I've got a UDF that interpolates data in a range. The problem with it is that if a part of the range does not contain data, it doesn't perform the calculation. Is there a way to firstly cull the range data and then do the math? Vlookup can work with a range of say C:D but this UDF can't.

Hi, My basic question is: Can the array inputs of the FORECAST function be read from an intermediate cell containing an OFFSET function? I am using the FORECAST function to interpolate between 2 pairs of numbers. I have the following formula which is working fine...

Hello, I wonder how can I get an access query to interpole kind of like in the VLOOKUP Excel formula. I have a table that have a field named GAP that shows the distance between tow measures. I have another table with 3 columns min, max and GAP_RANGE. I want the query to identify in which...
