5 min readHandling missing or invalid data is an important aspect of data analysis in MATLAB, as datasets often contain missing values or data points that are invalid or unusable. There are several ways to handle missing or invalid data in MATLAB, including:Removing missing or invalid data: One approach is to simply remove the data points that contain missing or invalid values.

8 min readData visualization in MATLAB is an essential skill for analyzing and interpreting data effectively. By creating appropriate visualizations, you can uncover patterns, trends, and insights that may not be readily apparent in raw data. Here are some methods to perform data visualization in MATLAB:Line Plot: Line plots are useful for displaying the relationship between two variables. You can use MATLAB's plot function to create a line plot by specifying the x and y coordinates.

7 min readThe Relative Strength Index (RSI) is a popular technical indicator used in day trading to analyze the strength and momentum of a price movement. It measures the speed and change of price movements on a scale from 0 to 100. Traders rely on the RSI to identify overbought and oversold conditions of a security, which can be used to determine potential turning points and generate buy or sell signals.

7 min readKotlin's coroutines are a powerful feature that allow for concurrent and asynchronous programming. They are designed to simplify the process of writing asynchronous code, making it easier to handle tasks that involve long-running or potentially blocking operations.To work with Kotlin's coroutines, you need to understand a few fundamental concepts. First, coroutines are lightweight threads that can be suspended and resumed at specific points in the code.

6 min readCreating and using classes in MATLAB allows you to organize your code into objects with their own properties and methods. Here are the basic steps to create and use classes in MATLAB:Create a new MATLAB class file by clicking on the "New" button in the MATLAB Editor and selecting "Class". Define the class name and save the file with a .m extension. Inside the class file, define properties using the properties block. Properties are variables associated with the class.

7 min readThe Guide to On-Balance Volume (OBV) in trading is a useful tool for technical analysis in the stock market. OBV is a momentum indicator that measures buying and selling pressure based on trading volume. It was developed by Joe Granville and gained popularity in the 1980s.OBV works on a simple principle: volume is assumed to be positive when the price closes higher, indicating buying pressure, and negative when the price closes lower, indicating selling pressure.

6 min readIn Kotlin, exceptions are handled using try-catch blocks, similar to other programming languages. The try block contains the code that may throw an exception, and the catch block handles the exception if it occurs.To handle exceptions in Kotlin:Place the code that might throw an exception within a try block.After the try block, add one or more catch blocks to handle specific exceptions.

6 min readWorking with collections in Kotlin involves manipulating and performing various operations on data structures that store multiple values. Kotlin provides a wide range of collection types, including lists, sets, and maps, each designed to serve different purposes.Lists:A list is an ordered collection of elements, and it allows duplicate values.To create a list, you can use the listOf() function, specifying the elements within the parentheses.

7 min readOptimizing code performance in MATLAB is crucial in order to enhance computational efficiency and minimize processing time. Here are some tips and techniques to achieve this:Vectorization: MATLAB performs operations quickly on large arrays rather than individual elements. Convert loops to vectorized operations whenever possible to benefit from this feature. Preallocate Arrays: MATLAB dynamically reallocates memory when arrays grow during execution.
