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.
Go to the File menu, click on New and then M-file. The MATLAB editor will open a new window. Insert a cell. (Type %% or click on the first %% icon on the last line of the tool bar or go to the Cell menu and click on Insert Cell Break) then Enter.You should now have a blank line.imple MATLAB Plots. The easiest way to plot a graph in MATLAB is with the command ezplot. It can take as input either a string or a symbolic expression. Thus ezplot('t^3-t', [-2, 2]) and syms t followed by ezplot(t^3-t, [-2, 2]) are both acceptable ways to plot over the interval where runs from -2 to 2.
