Sometimes you have repeating values in the column and you want to extract only their unique instances. The Remove Duplicates option is used to do this, and the UNIQUE is a new Excel function that has been built to perform the same thing. It generates a dynamic array with unique values, whether it contains text, numbers, dates …
The SEQUENCE is another function that manipulates dynamic arrays. It allows generation of an array of numbers within a vector or matrix, depending on the given parameters, and it is possible to set the initial value as well as the step value by which the series is being incremented. So, it’s something like when you use the Fill Series option, except that you can now do it with the function.
One of the previous “recipes” was about randomly generated numbers, ie the use of the RANDBETWEEN function. The RANDARRAY function works similarly to the fact that, unlike the one mentioned above, it generates a random range of numbers (vector or a matrix) based on previously specified rules. This is one of the new Excel functions that is available only to Office 365 subscribers. Let’s see how it is works!
For some time now, Microsoft “evangelists” have been talking about about new Excel functions that make it possible to work with dynamic arrays. What is it about? Excel is enriched with a group of functions that provide dynamic content filtering. Since they finally became an integral part of Office 365 Excel in February this year, the following few “recipes” will, through simple examples, show you the new features they bring.
For a given series we can add a trend line which, by applying the selected mathematical function, approximates and shows the trend of data, which was discussed in one of the earlier posts. By displaying the value of R2 we can see how well we chose the function that approximates the data. How else can you improve the trend line appearance?
