Y = sinh(X) returns the hyperbolic sine
of the elements of X. The sinh function
operates element-wise on arrays. The function accepts both real and complex inputs.
All angles are in radians.
The hyperbolic sine satisfies the identity . In other words, is half the difference of the functions and . Verify this by plotting the functions.
Create a vector of values between -3 and 3 with a step of 0.25. Calculate and plot the values of sinh(x), exp(x), and exp(-x). As expected, the sinh curve is positive where exp(x) is large, and negative where exp(-x) is large.
x = -3:0.25:3;
y1 = sinh(x);
y2 = exp(x);
y3 = exp(-x);

The sinh function
fully supports GPU arrays. To run the function on a GPU, specify the input data as a gpuArray (Parallel Computing Toolbox). For more information, see Run MATLAB Functions on a GPU (Parallel Computing Toolbox).
The sinh function can calculate on all variables within a table or
timetable without indexing to access those variables. All variables must have data types
that support the calculation. For more information, see Direct Calculations on Tables and Timetables.
