How to use the histfit function in MATLAB?

The histfit function is used to plot a histogram and fit a probability density function. This function displays the frequency distribution of a dataset as a histogram, and uses a fitting curve to approximate the probability density function of the dataset. It is used as follows:

In this function histfit(), data represents the input dataset, bins determines the number of bins in the histogram, and dist specifies the probability density function to fit.

The function will return two output parameters: the y value represents the height of each bar graph, and the x value is the center position of the bar graph.

Example Usage:
data = generateRandomNumbers(1000,1); % Generate 1000 random numbers following a normal distribution
plotHistogramWithFit(data, 20, ‘normal’) % Plot histogram and fit normal distribution curve
