Using Save Workspace

You can use Save Workspace if you have to interrupt your work, when you have several workbooks open at once. The Save Workspace command saves the current configuration of the workspace. Excel for the Macintosh proposes the filename RESUME. When you open the RESUME file, the workbooks will be restored to their former size and position on screen.

These files store the workspace or variables created during a session. All matrices, vectors and scalars with unique names are saved. Many chemometricians exchange data in this format. The command save places all this information into a file called matlab.mat in the current working directory. Alternatively, you can use the Save Workspace item on die File menu. Normally you wish to save the information as a named file, in which case you enter the filename after the save command. The following code saves the results of a session as a file called mydata in the directory c results, the first line being dependent on the current working directory and requires you to have created this first ... 

The time response of the CNC control system is also obtained using SIMUFINK as shown in Figure A1.3. Note that the variables t and xq have been sent to workspace, an area of memory that holds and saves variables. The commands who and whos lists the variables in the workspace. The system time response can be obtained by the command... 

When you stop work, save your m-files in a folder, so you can use them next time. You can also save the workspace, which will save all the numerical values that have been calculated. This is convenient if you have to interrupt your work for a short time and do not want to start over. Of course, most of your work is contained in your m-files, which you always want to save. 

Menu bar Contains the commands you can use to perform certmn tasks, for example, to save your workspace or to change the View settings. 

The module which can be used for pharmacophoie generation in this suite is Phase [53], Any number of ligands with their activity value (half maximal inhibitoiy concentration, ICj ) can be used for the generation of common pharmacophore, but always a set of compounds that are studied under similar experimental results will provide good results. For example, we have chosen few compounds which are known inhibitors of dihydroorotate dehydrogenase enzyme in Plasmodium falciparum [54]. This set of compoimds contains active and inactive compoimds (based on the ICjo values). Draw the molecules either in maestro workspace or in any tool like ChemSketch [55] or ChemDraw [56] and save them in. mol format. Now import these molecules into the project table (Fig. 4.56). 

We can save the workspace as a file (.mat) that can be loaded anytime. This is particularly interesting to save the results of a calculation. We can save it directly by clicking on the disk symbol over the workspace or using the command ... 

TuneUne—This is very similar to the timeline in the main program workspace. You can add markers and regions to a media file that will be saved with the file when you click the Save button at the top of the Track Properties window. See Chapter 3 for more information on using markers and regions in AQD. 

Another elegant way of saving the simulation to the workspace and then plotting the results proceeds as follows. Double click on the scope and select the Parameters option (second from the left). Select Data History and select the Save data to workspace option. Enter an appropriate name and select Array as format. Subsequently, select Apply and OK. After you run your simulation again, a variable with the name y will exist. The file y.mat contains three column, the first one is the time, the second one variable y 1, the second one variable y2. You can now use the plot command to visualize the process variables, for example plot (y( ,l),y( ,2), r, y( ,l),y( ,3), b ). 

It can be useful to export data to the workspace, in order to make plots, manipulate the data etc. (use a to workspace block and use the option save format array . In addition to the variable, an array with time points, tout is exported to the workspace). 

There are two types of m-files, functions and scripts. A MATLAB function has variables that can be passed into and out of the function. Any other variables used inside the function are not saved in memory when the function is finished. Scripts, on the other hand, save all their variables in the MATLAB workspace. Functions and scripts have names like myfunction.m. The first line of a function must contain a function declaration, using the following format ... 

The programs written in the language of MATLAB should be saved with the extension of m , from where the name of m-file comes. If you use the editor of MATLAB, it automatically saves your files with the w extension. Otherwise, be sure to save them with the m extension. M-files can be in the form of scripts ondi functions and could be executed in the MATLAB workspace. 

This function must be. saved as " myfunction.nC. You can now use this function in the workspace, in a script, or in another function. For example ... 

You can load your data into the MATLAB workspace using the load command. If the file to be loaded is generated by MATLAB (carrying .maf extension), the variables will appear in the workspace with their name at the time they were saved ...
