Hello everyone, thanks for reading my post.(adsbygoogle = window.adsbygoogle || []).push({});

Issue 1:

Example:

Suppose I want to draw a graph for sec θ=x + 1/4x

I want 'θ' on the y-axis and different values of 'x' on x-axis. Can I plot the graph using Matlab?

Issue 2: I want to know if it's possible to plot graph of complex mathematical functions after performing complex mathematical calculations(calculations involving Calculus, Algebra, Trigonometry, Probability), both done in the Matlab software. I want to do calculations and also graph plotting in Matlab. Is this possible in Matlab? I will be doing Digital and Analog Signal Processing and Analysis. Purpose is to analyze signals/graph and generate manipulated, random signals/graph. I only know that Matlab can do things like recognition/detection.

Please don't just tell me "Yes, you can draw graphs in Matlab".

Issue 3: I want to write some script and the function-in-question in Matlab such that when I give different values to the variables in the function it must display the corresponding graph. Can this be done, in Matlab?
