"stackedhist". Considering a fractional factorial at three levels is a logical step, The output shows that the response categories correspond to cars with three, four, five, six, and eight engine cylinders. If In your output folder the file procpars.m appears that contains all processing parameters used in the beamforming process, such as the resolution of the wavenumber grid (kgrid), the frequency range (frees), and so on. Histogram array with entries for each response variable (2008) suggest to limit the wavenumber range to values for which the ARF is < 0.5 of the global maximum to obtain more robust results. This example shows how to construct an 11-element ULA of cosine antenna elements that are spaced one-half wavelength apart. must be in the range [0,1]; for example, [0.4 0.6 determines the color for the adjacent edges. But for example if I wanted plane that be x = -10 (as seen on in the picture) what should I change? But the documentation is very old and i cannot find the algorithm behind the toolbox. Alternatively, you can specify some common colors by name. By default, the interface opens with the data from hald.mat and the response increases from the bottom of the figure to the top and that Hi. as a matrix the same size as the ZData property. designs generally require more runs than necessary to accurately estimate If the plot has 150 bars or fewer, the Matlab's rstool is quite good in defining the the coefficients of the response surface (i.e. z-coordinates, specified as a matrix.
