MATLAB Online에서 열기 im making a blackjack code where it selects a random element from the vector(deck), but after that value is called it cannot be called again in a seperate for statement. Thanks :) deck = [1:52];
R = mvnrnd(mu,Sigma,n) returns a matrix R of n random vectors chosen from the same multivariate normal distribution, with mean vector mu and covariance matrix Sigma. For more information, see Multivariate Normal Distribution. example R = mvnrnd(mu,Sigma) returns an m-by-d matrix R of ra...

You can vary the transparency of scattered points by setting the AlphaData property to a vector of different opacity values. To ensure the scatter plot uses the AlphaData values, set the MarkerFaceAlpha property to 'flat'. Create a set of normally distributed random numbers. Then create a ...
Matlab provides a wide range of graphics facilities which may be called from within a script or used simply in command mode for direct execution. We begin by considering the plot function. This function takes several forms. For example, plot(x,y) plots the vector x against y. If x and ...
这个示例使用了Kennard-Stone算法来选择样本。当然程序还提供了随机选择Random Sampling和SPXY算法。 把这80个样本分成40建模20验证20预测,切换到Sample Selection界面,参数设置如下图所示。 The KS algorithm is used to divide the available samples into calibration, validation, and prediction sets. The corn data...

NumPy also contains a number of useful methods for reading text and binary data files, fitting polynomial functions, many mathematical functions (sine, cosine, square root, and so on), and generating random numbers. The performance-sensitive parts of NumPy are all written in the C language, so...
