How to plot two heatmaps with the same cell height and width for two different Matrix (same column number but different row number) using heatmap.2 ?

Question

[FantasticAI]

Hi

I have two different matrix with the same column number but different row number. I would like to know if there is a general way to plot two heatmaps with the same cell height and width for two different matrix?

For example, Matrix 1 has 10 rows and 20 columns, and Matrix 2 has 100 rows and 20 columns, is there a general way to make sure any two matrix heatmap has the same cell height and width using heatmap.2?

Any helpful suggestions would be appreciated.
