Overload List
| Random | Creates a new matrix with uniform random numbers in the specified range. |
| Random | Creates a new matrix with uniform random numbers in the specified range. |
RandomUniform(Int32, Int32, Double, Double, ArrayMutability)
Creates a new matrix with uniform random numbers in the specified range.
public static DenseMatrix<double> RandomUniform(
int rowCount,
int columnCount,
double min,
double max,
ArrayMutability mutability = ArrayMutability.MutableValues
)Parameters
- rowCount Int32
- The number of rows in the new matrix.
- columnCount Int32
- The number of columns in the new matrix.
- min Double
- The lower bound of the uniform distribution (inclusive).
- max Double
- The upper bound of the uniform distribution (exclusive).
- mutability ArrayMutability (Optional)
- Specifies how the matrix's values may be changed. The default is mutable values.
Return Value
DenseMatrix<Double>A new DenseMatrix<T> with random values uniformly distributed between min and max.
Example
// Create a 3x4 matrix with values between -1 and 1
var m = Matrix.RandomUniform(3, 4, -1.0, 1.0);Exceptions
| Argument | rowCount or columnCount is less than zero. |
RandomUniform(Int32, Int32, Double, Double, Random, ArrayMutability)
Creates a new matrix with uniform random numbers in the specified range.
public static DenseMatrix<double> RandomUniform(
int rowCount,
int columnCount,
double min,
double max,
Random random,
ArrayMutability mutability = ArrayMutability.MutableValues
)Parameters
- rowCount Int32
- The number of rows in the new matrix.
- columnCount Int32
- The number of columns in the new matrix.
- min Double
- The lower bound of the uniform distribution (inclusive).
- max Double
- The upper bound of the uniform distribution (exclusive).
- random Random
- A random number generator used to generate samples.
- mutability ArrayMutability (Optional)
- Specifies how the matrix's values may be changed. The default is mutable values.
Return Value
DenseMatrix<Double>A new DenseMatrix<T> with random values uniformly distributed between min and max.
Example
// Create a reproducible 3x4 matrix with values between -1 and 1
var rng = new Random(42);
var m = Matrix.RandomUniform(3, 4, -1.0, 1.0, rng);Exceptions
| Argument | rowCount or columnCount is less than zero. |
| Argument | random is null. |
