The MATLAB functions log1p and expm1 calculate log (1 + x) and e x-1 accurately for very small values of x. For example, if you try to add a number smaller than machine precision to 1, then the result gets rounded to 1.
example. Y = exp(X) returns the exponential ex for each element in array X. For complex elements z = x + iy , it returns the complex exponential. e z = e x ( cos y + i sin y) . Use expm to compute a matrix exponential.
6 Μαΐ 2012 · a = log10(A); [v i] = max(ceil(abs(a))); exponent = v * sign(a(i)); this finds the maximum absolute exponent, and returns that. So if A = [1e-6 1e20] , it will return 20.
Syntax. C = A.^B. C = power(A,B) Description. example. C = A.^B raises each element of A to the corresponding powers in B. The sizes of A and B must be the same or be compatible. If the sizes of A and B are compatible, then the two arrays implicitly expand to match each other.
13 Μαρ 2023 · Step 1: we take variables and assign values. Step 2: then we use exp to get exponential values of the variable. Step 3: then we use a plot statement with appropriate syntax to plot the exponential graph to visualize the exponential data.
Description. Y = expint(X) evaluates the exponential integral for each element of X. Algorithm. For elements of X in the domain. , expint uses a series expansion representation (equation 5.1.11 in [1]): For all other elements of X, expint uses a continued fraction representation (equation 5.1.22 in [1]): References.
This example shows how to fit an exponential model to data using the fit function. The exponential library model is an input argument to the fit and fittype functions. Specify the model type 'exp1' or 'exp2'. Generate data with an exponential trend and then fit the data using a single-term exponential.
