8 min readTo write a function in MATLAB, you need to follow a specific syntax. Here is an explanation of how to write a function in MATLAB:Start by opening a new file in the MATLAB editor or any text editor of your choice. Begin the function definition by using the function keyword followed by the function name. Make sure the function name matches the name of the file. For example: function result = functionName(inputs) The function name should be meaningful and descriptive.

9 min readTo implement a census transform in MATLAB, you can follow these steps:Load the input image in MATLAB using the imread function. Make sure the image is in grayscale format for simplicity. Define the window size for the census transform. The window size determines the number of bits in the transformed image. For example, if you choose a window size of 3x3, the transformed image will have 8 bits. Create an empty matrix to store the transformed image.

6 min readIn MATLAB, you can access a power set by using the "powerSet" function or by manually generating all possible subsets of a given set. The power set of a set is the set of all possible subsets, including the empty set and the set itself.To access the power set of a set using the "powerSet" function, you need to provide the set as an input argument. The function will then return the power set as an output.

6 min readBollinger Bands are a popular technical analysis tool used by traders to analyze and identify potential opportunities in the financial markets. Created by John Bollinger in the 1980s, these bands consist of three lines located above and below a moving average line.The middle band is the simple moving average (SMA) of the price over a specified period, usually 20 days. The upper and lower bands are calculated by adding and subtracting a certain number of standard deviations from the middle band.

5 min readTo create a big matrix in MATLAB, you can use several methods:Preallocating a matrix: One common approach is to preallocate a matrix and then assign values to its elements. This is generally faster than dynamically expanding the matrix. For example, to create a 1000x1000 matrix filled with zeros, you can use the following code: matrix = zeros(1000, 1000); Initializing with a specific value: You can also initialize a matrix with a specific value using the ones function or any other desired value.

10 min readTechnical analysis is a popular method used by traders and investors to analyze stocks and forecast future price movements based primarily on historical market data. This approach is based on the belief that past price patterns and trends can help predict future price movements, disregarding fundamental factors such as a company's financial health or overall market conditions.

7 min readTo rotate a plot in MATLAB, you can use the "view" function. The "view" function allows you to change the viewing angle or orientation of a 3D plot.The syntax for the "view" function is as follows:view(azimuth, elevation)The "azimuth" parameter specifies the rotation of the plot from the x-axis in the horizontal plane. It ranges from -180 to 180 degrees, with positive values rotating the view counterclockwise.

10 min readThe Elder-Ray Index is a technical indicator developed by Alexander Elder to assist traders in determining the strength of bullish and bearish trends in the market. It is based on the concept that market movements consist of two phases - the "bull power" and the "bear power."To calculate the Elder-Ray Index, you need to follow these steps:Calculate the High-High (HH) and Low-Low (LL): Find the highest high and lowest low values over a specific period, typically 13 trading days.

4 min readTo save or print without displaying in MATLAB, you can use the command window's semi-colon (;) operator to suppress the output. The semi-colon tells MATLAB not to display the result in the command window. Here's how you can save or print without displaying:To save the result in a file without displaying: result = your_function(); % Perform some calculations or generate the result save('result.mat', 'result'); % Save the result in a MAT-file named 'result.
