UT Austin M 340L: Matrices and Matrix Calculations
M 340L is UT's applied linear algebra course: systems of equations, matrix algebra, vector spaces, eigenvalues, and orthogonality. It's required for CS and many engineering degree plans and emphasizes computation and application over formal proof.

What makes it hard
The mechanics are learnable; the conceptual vocabulary is the filter: span, linear independence, subspaces, and rank look like jargon until suddenly every exam question is phrased in them. Students who grind row reduction but skim the definitions hit a wall mid-semester when the questions stop being computational and start being is-this-true-and-why.
What you'll cover
- • Systems of linear equations and row reduction
- • Matrix algebra and inverses
- • Vector spaces and subspaces
- • Linear independence, basis, and rank
- • Eigenvalues and eigenvectors
- • Orthogonality and least squares
The M 340L study guide
How to study for UT Austin M 340L, step by step.
- 1
Learn the vocabulary as carefully as the mechanics
M 340L's exams are phrased in span, independence, and subspaces. Write each definition in your own words and test it against concrete examples the week you meet it.
- 2
Keep computations fast and quiet
Row reduction and eigenvalue mechanics should be automatic so exam time goes to the conceptual questions where the curve is decided. Short regular drills get them there.
- 3
Collect examples and counterexamples
A set that spans and one that doesn't, vectors independent and dependent: the why for each pair is exactly what true/false questions probe.
- 4
Connect concepts to their applications
Least squares, rank, eigendecomposition: knowing what each is for makes the abstractions stick and matches how this applied course frames its questions.

FAQ
Is M 340L hard at UT Austin?
The early computation is friendly, then the conceptual vocabulary (span, independence, subspaces) takes over the exams. Students who take the definitions seriously from week one find it manageable; mechanics-only students get caught mid-semester.
Do CS majors need M 340L?
Linear algebra is required for the UT CS degree, and M 340L is the standard way to satisfy it. The material also underpins graphics, machine learning, and data science coursework, so depth here pays forward.
How do I study for M 340L exams?
Two tracks: short drills to keep row reduction and eigen-computations fast, and example/counterexample work on the definitions for the conceptual questions. The true/false-with-justification style rewards understanding you can articulate.

M 408C: Differential and Integral Calculus
M 408C is UT Austin's accelerated first calculus course, covering differential calculus and a substantial dose of integral calculus in a single semester. It's the standard track for engineering, CS, and natural sciences majors, and it moves faster than the equivalent course at almost any other public university.
M 408D: Sequences, Series, and Multivariable Calculus
M 408D completes UT's accelerated calculus sequence, covering sequences and series, Taylor series, and a substantial introduction to multivariable calculus: vectors, partial derivatives, and multiple integrals. It's the second-semester course for the engineering and science track that began with 408C.
M 408K: Differential Calculus
M 408K is the first course in UT's standard-pace calculus sequence (408K, 408L, 408M), covering limits and differential calculus with thorough treatment of applications. It serves students who want the full calculus foundation without the compression of the 408C track.
M 408L: Integral Calculus
M 408L is the second course in UT's standard-pace calculus sequence, covering the definite integral, integration techniques, applications, and the introduction to sequences and series. It follows M 408K and precedes M 408M for students on the three-semester track.
