Day 254: NumPy Arrays — Creation and Indexing

Learning Objectives

• •**Create arrays** using `np.array`, `zeros`, `ones`, `linspace`, `arange`, `meshgrid`
• •**Understand dtypes** and choose appropriate precision for physics applications
• •**Reshape and transpose** arrays without copying data
• •**Apply slicing syntax** including multi-dimensional and negative indices
• •**Use fancy indexing** with boolean masks and integer arrays
• •**Recognize views vs copies** to avoid subtle bugs
• •**Discretize continuous functions** onto numerical grids
