![]() Let’s take a look at how to do this with the help of an example: VLOOKUP makes it effortless to look for an exact match from the table. How To Find an Exact Match Using VLOOKUP? In the next section, you will understand how to use the VLOOKUP function. The VLOOKUP formula below looks for a Company name with Company ID 3. Look at the example below to understand VLOOKUP. VLOOKUP in Excel may sound complicated, but you will find out that it is a very easy and useful tool once you try it. As the name specifies, VLOOKUP is a built-in Excel function that helps you look for a specified value by searching for it vertically across the sheet. If the value is TRUE, then we are looking for an approximate match. range_lookup: This has two options if the value is set to FALSE, that means we are looking for an exact match.col_index_number: This specifies the column number from where we need to return the value.table_array: This is the location where the values are present in excel.lookup_value: This specifies the value that you want to look up in our data.=VLOOKUP(lookup_value, table_array, col_index_number,) We can use the VLOOKUP function with the help of a simple syntax. Let’s go ahead and understand what exactly VLOOKUP in Excel is. VLOOKUP works as a search function by looking for specific data vertically across a table or spreadsheet. Often not appreciated for the range of tasks it lets the user perform, Microsoft Excel is undoubtedly a powerful and very popular tool used by almost every organization, even today.Įxcel provides an extensive range of functions that makes it easier to work with data. It helps users analyze and interpret data easily. Microsoft Excel is a deceptively powerful tool for data management. For this example, first let's create some *.Reviewed and fact-checked by Sayantoni Das Let's start with a simple problem and say we need to find a list of *.mat files given the folder. ![]() An applied function can either be anonymous, which is usually a case, or any regular function define in a *.m file. The idea is to take an array or cell class variable, loop through all its elements and apply a dedicated function on each element. This simple example provides an explanation on some functions I found extremely useful since I have started using MATLAB: cellfun, arrayfun. # Useful functions that operate on cells and arrays Then the graphics array can be saved using savefig like with a normal figure, but with the handle to the graphics array as an additional argument.Īn interesting side note is that the figures will tend to stay arranged in the same way that they were saved when you open them. This creates 3 scatterplots of random data, each part of graphic array h. H ( 1 ) = figure scatter ( rand ( 1, 100 ), rand ( 1, 100 ) ) h ( 2 ) = figure scatter ( rand ( 1, 100 ), rand ( 1, 100 ) ) h ( 3 ) = figure scatter ( rand ( 1, 100 ), rand ( 1, 100 ) ) savefig (h, 'ThreeRandomScatterplots.fig' ) close (h ) The following code creates an example figure that shows two lines a sin function and a threshold and a legend It turns out that the Line objects hold all data in following properties: XData, YData, and ZData the last one is usually 0 unless a figure contains a 3D plot. Once a line object has been found, get (opens new window) can return any value held by properties. findobj (opens new window) returns a handler to an object given attributes or properties of the object, such as Type or Color, etc. The key functions are findobj (opens new window) and get (opens new window). This example shows a trick how to achieve extract information from a figure. On a few occasions, I have had an interesting figure I saved but I lost an access to its data. You will be able to fold sections to have a general overview of your Then instead of seeing a long source code similar to : Sections are delimitedĮxample: To enable it check the "Sections" box: Note that folding is persistent, in the sense that part of the code that has been expanded/collapsed will keep their status after Matlab or the m-file has been closed and is re-open.Īn interesting option is to enable to fold Sections. Note that you can also expand or collapse all of the code in a fileīy placing your cursor anywhere within the file, right-click, and then select Code Folding > Expand All or Code Folding > Fold All from the context menu.Then you can choose which part of the code can be folded. To change folding preferences, go to Preferences -> Code Folding: Thus code folding can be set enable/unable for specific constructs (ex: if block, for loop, Sections. It is possible to change Code Folding preference to suit your need. # Useful tricks # Code Folding Preferences ![]()
