An example of a configuration function in SQL is the @@SERVERNAME function. This function provides the name of the local server that's running SQL. SELECT @@SERVERNAME AS 'Server' ServerSQL064 In SQL, most data conversions occur implicitly, without any user intervention. To perform any convers...

A common requirement for a Java application is that can be deployed by copying a single file. For simple applications that depend only on the standard Java SE class libraries, this requirement is satisfied by creating a JAR file containing all of the (compiled) application classes. Things are not ...

While coding a script or a function, it can be the case that one or more than one temporary file be needed in order to, for example, store some data. In order to avoid overwriting an existing file or to shadow a MATLAB function the tempname function can be used to generate a unique name for a te...

There can be up to 12 independent variables, there is always 1 dependent variable, and any number of parameters can be fitted. Optionally, error estimates can be input for weighting the data points. (T. Williams, C. Kelley - gnuplot 5.0, An Interactive Plotting Program) If you have a data set a...

If you load your fit parameters from a file, you should declare in it all the parameters you're going to use and, when needed, initialise them. ## Start parameters for the fit of data.dat m = -0.0005 q = -0.0005 d = 1.02 Tc = 45.0 g_d = 1.0 b = 0.0100...

The basic use of fit is best explained by a simple example: f(x) = a + b*x + c*x**2 fit [-234:320][0:200] f(x) ’measured.dat’ using 1:2 skip 4 via a,b,c plot ’measured.dat’ u 1:2, f(x) Ranges may be specified to filter the data used in fitting. Out-of-range data points are ignored. (T. W...

SQL has two logical functions – CHOOSE and IIF. The CHOOSE function returns an item from a list of values, based on its position in the list. This position is specified by the index. In the syntax, the index parameter specifies the item and is a whole number, or integer. The val_1 … val_n paramete...

When you have defined the basic layout of the application and acquired necessary permissions, the final step is to initialize the instance of the MapFragment class, thus creating and associating a Map with the MapFragment declared in the activity_main.xml file. public class BasicMapActivity extends...
