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.

7 min readPrice Rate of Change (ROC) is a technical indicator used in trading and scalping strategies to measure the speed of price movements. It calculates the percentage change in price over a specified period of time, allowing traders to identify the momentum of a financial instrument.In scalping, where traders aim to make small profits from quick price movements, the ROC indicator can be particularly useful.

7 min readMATLAB is a powerful software tool that can be used for various machine learning tasks. Here is an overview of how to use MATLAB for machine learning:Importing and preprocessing data: MATLAB provides easy-to-use functions to import data from various sources such as CSV files, spreadsheets, or databases. You can also preprocess the data by handling missing values, normalizing features, or performing feature selection.

7 min readThe Triple Exponential Average (TRIX) is a technical indicator used in trading to identify trends and provide trading signals. It is a momentum oscillator that focuses on smoothing out price data while also removing market noise.TRIX is based on a triple exponentially smoothed moving average of the price and aims to detect changes in the direction and strength of a trend.

7 min readTo create classes in Kotlin, you can follow these steps:Start by using the class keyword, followed by the name of the class. class MyClass { // class body } Inside the class body, you can declare properties, functions, and other elements. To declare properties, use the val or var keywords followed by the property name and its type. class MyClass { val myProperty: Int = 10 } To declare functions, use the fun keyword followed by the function name, parameter list (if any), and return type (if any).

11 min readSignal processing in MATLAB involves manipulating and analyzing signals to extract useful information. Here are some key steps to perform signal processing in MATLAB:Importing and Generating Signals: MATLAB allows you to generate signals using built-in functions or import them from external sources such as audio or video files. The signals can be in the form of time-domain or frequency-domain representations.
-
7 min readIn Kotlin, you can define functions using the keyword fun. Here is the syntax: fun functionName(parameters): returnType { // Function body // Perform operations and return a value if applicable } Let's break down each component:fun: This keyword indicates that you are defining a function.functionName: Replace this with the name you want to give your function. Choose a descriptive name that represents what the function does.

9 min readTo implement image processing algorithms in MATLAB, you can follow these steps:Obtain an image: Start by loading an image into MATLAB using the imread function. Ensure that the image is in a format supported by MATLAB (e.g., PNG, JPEG). Preprocess the image: Convert the image into the appropriate format for processing. You can adjust the color space, resize, crop, or perform other necessary preprocessing steps using MATLAB's built-in functions.

8 min readThe Ichimoku Cloud is a technical analysis indicator that is used to identify potential support and resistance levels, as well as trend direction in the financial markets. It consists of several components that are calculated using specific formulas.Tenkan-Sen (Conversion Line): This line is calculated by taking the highest high and lowest low over the past nine periods and then dividing it by two. It reflects the short-term trend of the market.
