I want to plot a gaussian distribution of a set of data and see the mean and 3 sigma. I am using the below code but I am not getting the gaussian curve. Please help! Thanks! x = [2.9954E-09,3.1314E-09,3.1155E-09,3.0940E-09,2.8861E-09,3.0875E-09,2.9685E-09,3.0532E-09,2....
points fall near the line, an assumption of normality is reasonable. Otherwise, an assumption of normality is not justified. For example, the following generates a data sample of 100 random numbers from an exponential distribution with mean 10, and creates a normal probability plot of the data....
plot(multinomialpd) The plot contains a Stem object that represents the probabilities for the data. Plot the pdf as a continuous distribution. Get plot(multinomialpd,Discrete=0) Plot the cdf of the fitted multinomial distribution as a stairs plot. Get plot(multinomialpd,PlotType="cdf") Plot...

Vector and Matrix Data bubblechart(x,y,sz) displays colored circular markers (bubbles) at the locations specified by the vectors x and y, with bubble sizes specified by sz. To plot one set of coordinates, specify x, y, and sz as vectors of equal length. To plot multiple sets of coordi...
Evaluate and plot the pdf values of the distribution. Get x_values = 50:1:250; y = pdf(pd,x_values); plot(x_values,y) Create a histogram with the normal distribution fit by using the histfit function. histfit uses fitdist to fit a distribution to data. Get histfit(x) The histo...
数据的美不仅限于直线世界,极坐标图以它独特的视角,描绘出了数据的周期性和对称美。Matlab中的polar函数或者polarplot函数,能够将数据点分布在极坐标系中,如同一朵朵绽放的鲜花,展示出角度与距离的关系,让周期性现象的规律变得触手可及。 The beauty of data is not limited to the straight line world. The pola...
