This header provides lazy-evaluated mathematical functions for tensor-like objects, implemented as expression templates. All operations are element-wise and maintain the original tensor's shape and strides.

Includes the following mathematical functions:

• Basic functions:
  • log() - Natural logarithm (ln)
  • exp() - Exponential (e^x)
  • sqrt() - Square root (√x)
  • abs() - Absolute value (|x|)
• Trigonometric functions (radians):
  • sin() - Sine
  • cos() - Cosine
  • tan() - Tangent
• Hyperbolic functions:
  • sinh() - Hyperbolic sine
  • cosh() - Hyperbolic cosine
  • tanh() - Hyperbolic tangent

Part of the Tannic Tensor Library.
