Multi-Dimensional Array Procedures
All:
First let me say that I am a programming neophyte, but I still need your assistance. I have tried to do my homework; however, I am certain that I am missing something. My goal is to: 1. Read a range into a multi-dimensional array, 4 columns by 500 rows. Each column is or could be an array within the multi- dimension array. 2. Modify input data such that the original array is different than the current. 3. Add the original array to the modified array. 4. Repeat this addition of previous array and current array for a fixed number of iterations. 5. Write the cumulative summation array to a worksheet. My challenges a 1. How to create and test a multi-dimensional array. 2. How to add two multi-dimensional arrays. 3. How to write a multi-dimensional array to a worksheet. Any guidance would be greatly appreciated. Here is what I have so far: Sub BuildCompositeProductionProfiles() Dim NumberOfPatterns As Integer Dim NumberOfForecastedMonths As Integer Dim OilRateArray As Variant Dim WaterRateArray As Variant Dim GasRateArray As Variant Dim InjWaterArray As Variant Dim AllStreamsArray() As Variant 'Initialize counters NumberOfPatterns = 75 NumberOfForecastedMonths = 500 'Call routine to build multi-dimensional array Call BuildAllStreams(AllStreamsArray, NumberOfForecastedMonths, OilRateArray, WaterRateArray, GasRateArray, InjWaterArray) End Sub Sub BuildAllStreams(AllStreamsArray, NumberOfForecastedMonths As Integer, OilRateArray, WaterRateArray, GasRateArray, InjWaterArray) Dim AllStreamsRange As Range With Worksheets("ThruPut") Set AllStreamsRange = .Range("AO8:AR" & NumberOfForecastedMonths + 7) End With AllStreamsArray = Application.Transpose(AllStreamsRange) [Error #1] ReDim Preserve AllStreamsArray(1 To NumberOfForecastedMonths) [Error #2] [Error #3] 'Dim i As Integer 'For i = LBound(AllStreamsArray) To UBound(AllStreamsArray) 'Debug.Print AllStreamsArray(OilRateArray(i), WaterRateArray(i), GasRateArray(i), InjWaterArray(i)), i 'Next i End Sub Floyd |
