• find, minerr—Solves a linear or nonlinear system of equations. The minerr function returns an approximate solution when find returns an error.

• minimize, maximize—Minimizes or maximizes a function.

• odesolve—Solves ODEs in solve blocks.

• Most of the solve block functions work only inside solve blocks. minimize and maximize work inside and outside solve blocks.

• Symbolic evaluation of functions is not supported inside solve blocks.

• Unlike other built-in functions, you can type the solve block function names with an initial uppercase or lowercase letter. Find and find are the same function.

• When you insert a solve block function, it is automatically assigned the Keyword label.

• The solver that a solve block function calls depends on whether the problem is linear or nonlinear, and on other factors. You can choose a solving algorithm for solve block functions. Read more about choice of solving algorithms here.
