In summary, a Quick Questionmatrix is a research tool used to gather data and insights from participants through a series of quick and concise questions in a multiple-choice format. It is similar to other survey methods but differs in its focus on efficiency and use of multiple-choice questions. The benefits of using a Quick Questionmatrix include efficient data collection and analysis, ease of understanding for participants, and a larger sample size. However, there are limitations such as the inability to gather in-depth responses and the reliance on accurate understanding and responses from participants. It can be used in various fields of research, making it a versatile tool.

not in general

similar matricies have the same eigenvalues

row operations, with the exception of row addition lead to changes in the eigenvalues and so the determinant of the matrix they are applied to
