How to generate a Sine with parameter input and output pre determined?
Hello, I need to generate 3 million files based cuvas with values X, Y (Time, Amplitude) of type Float for both.
How can I make a function that I indicate the time, amplitude, and get a txt file of data for each curve?

Given a sinusoid of the form “y = A * sin(w * x)”, I’m assuming you want the function to take “A” and “w” as parameters. The code below also assumes that “x” will span one period. The results will be saved as a text file based on the given name “outputFile”.
Edit: Based on your comment, it seems that you want to be able to control the amplitude, period, start time, and end time. In that case it seems like the following function should give you the correct results. "A" represents the amplitude, "T" represents the period, and "t" represents a vector that contains all of the time values.
function sineFunction(A, w, t, outputFile)
y = A * sin(t * 2 * pi / T);
save(outputFile, 't', 'y', '-ASCII');
Here is the function call you would make for the example you gave:
sinFunction(180, 10, 0 : 0.01 : 5, 'out.txt');
