Description

Fill vector with pseudorandom numbers from a normal distribution.

Syntax

BOOL Normal( int nSize, int nSeed = 0 )

Parameters

nSize: [input] number of values
nSeed: [input] seed for the random sequence. Using a value of 0 will generate a different sequence each time this function is called. The same senquence of numbers will be generated each time if the function is called with a fixed seed value larger than 0.

Return

Returns TRUE on success or FALSE on failure.

Examples

EX1

void vectorbase_Normal_ex1()
{
    // Declare a vector of size 20
    vector vec(20);
    // Fill with normal random numbers
    BOOL bRet = vec.Normal(vec.GetSize());
    // Output the values
    for( int ii=0; ii<vec.GetSize(); ii++ )
        printf("vec[%d]=%f\n", ii, vec[ii])
}

Remark

Fill vector with pseudorandom numbers from a normal distribution with zero mean and unit standard deviation. This method is similar to the LabTalk Normal function.

If this method is used on an integer vector, then the resulting vector will be filled with nearest integers from the distribution with typical values betwen -3 and 3.
