• Action • Make necessary corrections. Dimension ERROR (MATRIX and VECTOR Modes only) • Cause • The matrix or vector you are trying to use in a calculation was input without specifying its dimension. • You are trying to perform a calculation with matrices or vectors whose dimensions do not allow that type of calculation. • Action • Specify the dimension of the matrix or vector and then perform the calculation again. • Check the dimensions specified for the matrices or vectors to see if they are compatible with the calculation. Variable ERROR (SOLVE feature only) • Cause • You did not specify a solution variable, and there is no X variable in the equation you input. • The solution variable that you specified is not included in the equation you input. • Action • The equation you input must include an X variable when you do not specify the solution variable. • Specify a variable that is included in the equation you input as the solution variable. Can't Solve Error (SOLVE feature only) • Cause • The calculator could not obtain a solution. • Action • Check for errors in the equation that you input. • Input a value for the solution variable that is close to the expected solution and try again. Insufficient MEM Error • Cause • There is not enough memory to perform your calculation. • Action • Narrow the table calculation range by changing the Start, End, and Step values, and try again. Time Out Error • Cause • The current differential or integration calculation ends without the ending condition being fulfilled. • Action • Try increasing the tol value. Note that this also decreases solution precision. E-70
