Method Detail

lim

public static float lim(float max,
                        float x,
                        float min)

cos

public static float cos(float x)

A cos for float accuracy should be provide. Its return value should be float too. The implementation may be optimized or not, on machine/GPU-level.

Parameters:

x -

Returns:

cos

public static double cos(double x)

Wrapper surround standard cos for double. No effort on optimized javac-Compiler.

Parameters:

x -

Returns:

sin

public static float sin(float x)

A sin for float accuracy should be provide. Its return value should be float too. The implementation may be optimized or not, on machine/GPU-level.

Parameters:

x -

Returns:

sin

public static double sin(double x)

Wrapper surround standard sin for double. No effort on optimized javac-Compiler.

Parameters:

x -

Returns:

tan

public static float tan(float x)

tan

public static double tan(double x)

sqrt

public static float sqrt(float x)

sqrt

public static double sqrt(double x)

vec2RST

public static float vec2RST(float[] rst,
                            float[] s,
                            float[] t)

Outputs the 3 elements from a vector to 3 scalar. For example for a 3-phase voltage (named RST)

Parameters:

rst - the vector, should have (at least) 3 elements.

s - second output, S-phase

t - third output, T-phase

Returns:

first output, R-phase.
