In organic chemistry, a hydrocarbon is an organic compound consisting entirely of hydrogen and carbon, and thus are group 14 hydrides. Hydrocarbons, from which one hydrogen atom has been removed, are functional groups called hydrocarbyls. Because carbon has 4 electrons in its outermost shell carbon has exactly four bonds to make, and is only stable if all 4 of these bonds are used. Aromatic hydrocarbons, alkanes, cycloalkanes and alkyne-based compounds are different types of hydrocarbons. Most h
MATLAB's std function will return the standard deviation of a distribution, so we just have to divide this by the square root of the sample size to get the standard error of the mean (SEM). The standard deviation describes the spread of a sample distribution. The SEM describes certainty with which we know the mean of the underlying population based upon our sample of it. More specifically, the SEM is the theoretical standard deviation of the sample-mean's estimate of a population mean. To make the SEM more informative we can convert it to a confidence interval.
VBA code. A. Built-in MATLAB function. The VBA code below uses the trapz function of MATLAB in order to perform numerical integration using the trapezoidal rule. So, although in Excel you might need a custom VBA function to perform numerical integration, in MATLAB environment this is done by using a simple built-in function.
