Matlab
+ no references: arrays are values
+ building arrays -- use $[$, $]$!
  + row versus column vector; rectangular 2-D arrays
  + scalars, e.g. 1
  + start:end, start:step:end
  + horizontal concatenation, e.g. [ 1 2 3 ]
  + vertical concatentation, e.g.  [ 1; 2; 3 ]
  + zeros, ones, rand
  + strings or $char$ arrays
  + full(sparse(i,j,s,m,n))
+ arrays operations and functions operate on entire arrays: 
      ', +, -, .*, ./, .^
      length, size
      abs, sqrt, sum, prod, min, max, rem, round, floor, ceil
+ logical arrays
  + 1 for true, 0 for false
  + relational operations: <, <=, >=, >, ==, ~=
  + boolean operations: ~, &, |
  + can be used for indexing
  + can be used for counting
+ indexing a(positionsWeCareAbout), a(rowsWeCareAbout,columnsWeCareAbout):
  + for fetching elements
  + for assignment to elements
  + $:$ means "all of them"
  + duplicate positions are allowed; any order is allowed
  + can use logical arrays for indexing
+ assignment
  + indexing allows assignment to many elements
  + assigning an empty array deletes elements, e.g. x(1) = []
  + assigning a scalar copies the scalar to each element
+ conditionals and loops: if, for, while
+ functions:
  + remember to include a specification comment
  + one function per file with same name as function
  + assign to the return *variable(s)* the return value(s)
  + syntax: function "return-variables" = "function-name" ("parameters")
