Morphology
The meaning 'the branch of algebra concerned with matrices' is directly and transparently derived from combining 'matrix' (a rectangular arrangement of numbers) with 'algebra' (a branch of mathematics). This noun–noun compositional pattern is regular and cross-linguistically common, so a B1 learner who knows both constituents would readily infer the MWE's meaning.
Etymology
Matrix algebra comes from the word matrix, which long ago meant a 'place where something is formed', and from algebra, meaning the 'rules for working with numbers'. People began using matrix for a grid of numbers that can 'shape' or change other numbers, so matrix algebra means the 'rules for working with number grids'.
