• List, matrix, and vector calculation errors
When you see
It means this:
this message:
Invalid List, Incorrect use of a list, matrix, or vector.
Matrix or
Vector
Dimension Illegal dimension used during matrix,
ERROR vector, or list calculations.
Complex List containing complex number used
Number in List in a calculation or operation for which
complex number data is invalid.
Complex Matrix containing complex number
Number in used in a calculation or operation for
Matrix which complex number data is invalid.
Complex Matrix or vector containing complex
Number In number used in a calculation or
Matrix or operation for which complex number
Vector data is invalid.
Improper You attempted to create a list, matrix,
Number of or vector whose number of elements
Elements exceeds the maximum limit.
• Equation mode errors
When you see
It means this:
this message:
Infinitely Many An infinite number of solutions for
Solutions simultaneous linear equations.
No Solution No solution for simultaneous linear
equations.
No Variable No variable within a Solve equation.
So you need to do this:
Press J to display the error and
make necessary corrections.
Check the matrix, vector, or list
dimension.
Change all data in the list to real
numbers.
Change all data in the matrix to real
numbers.
Change all data in the matrix or
vector to real numbers.
A list cannot have more than 999
elements, and a matrix cannot
exceed 999 rows × 999 columns.
For vector elements, specify within 1
row × 999 columns or 999 rows × 1
column.
So you need to do this:
Input a Solve equation that includes
a variable.
