• 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.
