INDEX worksheet

You can use the MATCH and INDEX worksheet functions in a formula to perform linear interpolation in a table. The syntax of the MATCH function is MATCH lookup value,lookup array,match type). If match type = 1, MATCH returns the position of the largest array value that is less than or equal to... 

The Function procedure in Figure 15-10 is identical to Excel s INDEX worksheet function it passes a range and a number as arguments and returns the xth. element of the array.

You can select individual values in an array by using the INDEX function, but this is a "read-only" option. If you need to be able to change individual values in an array, you should enter the values in a range of worksheet cells, rather than as an array. 

Any of the four worksheet formulas described below can be used to select every Nth data point from a data table. All four utilize the INDEX(array, row num,column num) function to select an element from the array of data, but they use different methods to calculate the pointers row num and column num into the reference that contains the data. 

Excel Tip. Since worksheet ranges, worksheet functions and worksheet arrays use (or assume) a lower array index of 1, you should always include the Option Base 1 statement at the beginning of each code module that uses arrays. 

The lower index of these arrays is always 1. Although arrays created within VBA have a lower array index of zero unless specified otherwise (by means of the Option Base 1 statement, for example), when you transfer a range of cells from a worksheet to VBA, an array is created with lower array index of 1. 

If you use a worksheet function within VBA that returns an array, the lower array index will be 1. Such worksheet functions include LI NEST, TRANSPOSE, MINVERSE, MMULT. Other functions that return arrays include the VBA function Caller when used with a menu command or toolbutton. 

Object can be Worksheet or Range. Index is the name or number (column A = 1, etc.) of the column. 

Development Worksheet for SPE (Fig. 3.2). The structure for atrazine shows that it contains a triazine ring with two secondary amines. The aqueous solubility is 33 mg/L, and the compound is quite soluble in methanol, ethyl acetate, and chloroform. List these solvents on the worksheet in Figure 3.2 as possible elution solvents. The pA", of atrazine is not given in the Merck Index, but a quick literature search shows that the is less than 2.0. Furthermore, the compound is stable in water and the pH range of samples will be from 5 to 8. This information may be recorded on the worksheet together with the pAT, and pH of the sample. 

Holden, H., Design Density Index, HP DFM Worksheet, Hewlett Packard, April 1991. 

Table 5.8 shows what a typical worksheet might look like for a laboratory that handles hazardous gases. Note that this worksheet includes a position for the facility risk index. As you can see, if the control is implemented, then the FRI changes. Again, it is very important to include verification of control. This is what ensures that your control is adequate to control the hazard, and it is something that can be verified to be in place. 

There is one more reason to introduce the system index into Mathcad. As we noted earlier, the worksheet may contain different variables of the same name. This is a typical example beside of those shown above - the conventional mathematical notation f = f (x) the variable f is assigned the value of function f with the argument value saved as variable x. To avoid errors these two objects must be... 

As will be discussed in Sect. 6.5, Mathcad worksheet is three-dimensional. That allows us to overlap the variable name by a picture, its graphic pseudonym, and remove the restrictions on the variable names, for example, insert a period of two indexes...
