Description

Fill vector with pseudo random numbers between 0 and 1.

Fill vector with value randomly picked from the given vectorbase object

Syntax

BOOL Uniform( int nSize, int nSeed = 0 )

BOOL Uniform( int nSize, vectorbase & v, int nFillFrom = -1 )

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.

nSize: [input]the number of elements to be filled
v: [input]vectorbase object to offer the value
nFillFrom: [input]start index of vector to fill values to

Return

Returns TRUE on success or FALSE on failure.

TRUE on success, otherwise FALSE

Examples

EX1

void vectorbase_Uniform_ex1()
{
    // Declare a vector of size 20
    vector vec(20);

    // Fill with random numbers
    BOOL bRet = vec.Uniform(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 pseudo random numbers between 0 and 1 from a uniform distribution. This method is similar to the LabTalk Uniform function. If this method is used on an integer vector, then the resulting vector will be filled with 0s.
