How-to Guide

1. Enter the MMULT function

Entry point: Formulas tab → formula bar

  1. Open WPS Spreadsheet and select the cell where you want the result to appear.
  2. Type = to start the formula.
  3. Type MMULT(.
  4. Review the syntax prompt that appears and confirm that the function entry state is active.

Success Criteria

  • Interface result: The formula bar or selected cell shows =MMULT(.
  • Next action available: You can continue entering arrays, ranges, or references.

Tips While Using

  • Common mistake: If you do not start with =, the content may be treated as plain text.
  • Environment note: You need to be in an editable spreadsheet cell.

2. Fill in the function arguments

Entry point: formula bar

  1. After MMULT(, enter the first array or cell range.
  2. Enter the argument separator.
  3. Enter the second array or cell range.
  4. Check that the number of columns in the first matrix matches the number of rows in the second matrix.
  5. Type the closing parenthesis and press Enter.

Success Criteria

  • Interface result: The cell returns a calculation result, and the full formula appears as =MMULT(argument1,argument2) or the local separator format.
  • Next action available: You can revise the referenced ranges and calculate again.

Tips While Using

  • Common mistake: Unclosed parentheses, incorrect separators, or mismatched dimensions can cause an error.
  • Environment note: The referenced ranges should contain numeric data for calculation.

3. Use cross-sheet references and nested calculations

Entry point: formula bar

  1. In the MMULT arguments, select data ranges from the current worksheet or another worksheet.
  2. When you need a compound formula, place MMULT inside a longer formula expression.
  3. Check that the referenced ranges are correct and do not point to blank or text cells.
  4. Press Enter to confirm the formula.

Success Criteria

  • Interface result: The formula shows worksheet references or a nested structure.
  • Next action available: You can modify the source ranges and observe result changes.

Tips While Using

  • Common mistake: Selecting the wrong worksheet range changes the result.
  • Environment note: Referenced worksheets should keep valid data ranges.

4. Check results and automatic recalculation

Entry point: result cell and source data range

  1. Review whether the MMULT result matches your expectation.
  2. Change the source data used in the calculation.
  3. Observe whether the result cell updates automatically.
  4. If the result looks incorrect, check for text-formatted numbers, blank cells, or circular references.

Success Criteria

  • Interface result: The result updates when the source data changes.
  • Next action available: You can continue adjusting data and validating the output.

Tips While Using

  • Common mistake: Numbers entered as text may affect the calculation result.
  • Environment note: In complex formulas, check references and matrix dimensions first.
