Thermal voltage for a given temperature t in Kelvin Inverse Fast Fourier Transform of vector xĭiscrete Fourier Transform of function v(t) interpreting it physicallyĮlectronics Functions Unit Conversion dB(x) Inverse Discrete Fourier Transform of vector x Inverse Discrete Fourier Transform of function V(f) interpreting it physically To move the frequency 0 to the center of the vector Shuffles the FFT values of vector x in order Integrate vector x numerically assuming a constant step-size h Returns the y-value of the given vector f which is located nearest to the x-value xval therefore the vector f must have a single data dependencyĭata Analysis: Differentiation and Integration ddx(expr,var)ĭerives mathematical expression expr with respect to the variable varĭifferentiate vector y with respect to vector x n times. Returns the x-value which is associated with the y-value nearest toĪ specified y-value yval in a given vector f therefore the vector f must have a single data dependency Minimum value in vector if a range is given then x must have a single data dependencyĭata Analysis: Basic Operation cumprod(x)Įquidistant spline interpolation of real function vector f(x) using n equidistant datapoints the latter can be omitted and defaults to a reasonable value Maximum value in vector if a range is given then x must have a single data dependency Returns the greater of the values x and y
