31.01.2012 · I want to create a row vector from a certain range between two limits. So, given the limits 'a' and 'b', I do: x = [a:0.1:b] %I obtain a vector with equally spaced values between 'a' and 'b', with a 0.10 step. The problem is that now, I need to elevate each value of 'x' to square, and so, obtain a new vector, let's say 'y', that will contain ...

This MATLAB function returns the secant function of X. Secant Function for Numeric and Symbolic Arguments. Depending on its arguments, sec returns floating-point or exact symbolic results.
Y = sec (X) returns the secant of the elements of X. The sec function operates element-wise on arrays. The function accepts both real and complex inputs. For real values of X, sec (X) returns real values in the interval [-∞, -1] and [1, ∞]. For …

Y = sec( X ) returns the secant of the elements of X . The sec function operates element-wise on arrays. The function accepts both real and complex inputs.
I am trying to plot sin^2(x) together with cos^2(x) between [0,2pi]. but cant get my matlab to accept sin^2(x). here is what I wrote, what am i doing wrong?
Matlab provides inbuilt functionality for creating the matrix and assigning the values to it. There are several mathematical and trigonometric computations supported by Matlab software. Some of the arithmetic operations on the matrix in Matlab are addition, subtraction, multiplication.
MATLAB supports a subset of TeX markup. Use TeX markup to add superscripts and subscripts, modify the text type and color, and include special characters. MATLAB interprets the TeX markup as long as the Interpreter property of the text object is set to 'tex' (the default).

Duty Cycle of Square Wave. Open Live Script. Generate a 30 Hz square wave sampled at 1 kHz for 70 ms. Specify a duty cycle of 37%. Add white Gaussian noise with a variance of 1/100. t = 0:1/1e3:0.07; y = square (2*pi*30*t,37)+randn (size (t))/10; Compute the duty cycle of the wave. Plot the waveform and annotate the duty cycle.
Hyperbolic Secant. The hyperbolic secant of x is equal to the inverse of the hyperbolic cosine. sech ( x) = 1 cosh ( x) = 2 e x + e − x. In terms of the traditional secant function with a complex argument, the identity is. sech ( x) = sec ( i x) .
