You should be familiar with the following Matlab programming constructs and functions. I've marked issues on which I expect some confusion with (!).

  compact scientific notation (e.g. 1.4e-06)
  complex numbers (e.g. 3 + 4*i)
  Inf, NaN (!)

  =           assignment
  - + * / ^   algebraic operations
  \           solve system of equations Ax=b  (x = A\b)

  commas and semicolons
  how to write a row vector
  how to write a col vector
  how to write a matrix
  how to write a complex number
  
  accessing elements of vectors and matrices
    (single elements, rows, columns, and subsets (!))
     
  linear algebra operations on vectors and matrices
    + - * \ ^ '
  
  elementwise operations on vectors, matrices (!)
    - + .* ./ .^
 
  logical (boolean) operations
    == (!)
    ~= (!)
    >
    <
    >=
    <=
    ~   (!)
    &&  (simple AND)
    ||  (simple OR)
    &   (componentwise AND for vectors)
    |   (componentwise OR  for vectors)
    xor (for both vectors and simple logical variables) (!)
    zero    means false    
    nonzero means true

    any 
    all
    find

    square brackets [ ] 
    colon syntax
    linspace

  plotting functions
    plot
    semilogy
    semilogx
    loglog
    hist
    xlabel
    ylabel
    title 
    legend
    axes
    hold, hold off, hold on
    clf
    grid off, grid on
    color & marker codes
    figure

  scripts

You should be able to

• interpret various log-linear plots as x-y relationships of the form , , , and (!)
• convert linear story problems into matrix-vector equations and solve them
• write Matlab code for constructing plots of functions, with labels, legends, and specified line styles and colors
