I have a Netcdf file that has latitude, longitude and variable. The latitude is 1800x1 single, longitude 3600x1 single and the variable is 3600x1800 single. My objective is to plot the variable in the colorbar axis with the latitude as the y-axis and the longitude as the x-axis...
Plot a cdf of the normal distribution fit to the data and a stairs plot of a cdf for the data. Get plot(normalpd,PlotType="cdf") Display a probability plot for the normal distribution fit to the data. Get plot(normalpd,PlotType="probability") The vertical axis is scaled so that ...
h=kstest(x,CDF,0.05)检验样本x是否服从由Cdf定义的连续分布。显著性水平为0.05。 kstest2函数用来作两个样本的KS检验,它可以做双侧检验,检验两个样本是否服从相同的分布,也可以做单侧检验,检验一个样本的分布函数是否在另一个样本的分布函数之上或之下,这里的分布是完全确定的,不含有未知参数。

MATLAB high-level functions simplify the process of importing data from a NetCDF file or an OPeNDAP NetCDF data source. MATLAB low-level functions enable more control over the importing process, by providing access to the routines in the NetCDF C library. To use the low-level...
See Create and Manage Data Sets. Create a new fit for your data. See Create a New Fit. Display the results of the fit. You can choose to display the density (pdf), cumulative probability (cdf), quantile (inverse cdf), probability plot (choose one of several distributions), survivor ...
plotEmpiricalCDF(DDiagnostics) By default, plotEmpiricalCDF plots the ecdf of the baseline and target data for the variable with the lowest p-value, which is x2 in this case. You can see the difference between the two empirical cumulative distribution functions. The plot also displays the p-...
