How to color a matrix based on the values in matlab?

I have a matrix of 9 by 5. I want to colur them in a table so that the higher values got red and the lowest got yellow. The intermediates are needed to be coloured with much less intense colours. So that i can just look into the colured table and can find the extreme values.
Here is a sample matrix
A = [0.7637612466433112,1.1142257017424961,0.2706813336848490,0.6354189964764154,30.6379671624144230,11.8049168799568474,15.7338944060010970,18.0052089219629146,1.5550130243814884

Here are some possible solutions
- just to expand the horizontal size of the figure.
- rotate your matrix if there are much less columns than rows.
- round your values so they only have 1 decimal place - that will make shorter strings.
- just use the color bar to estimate the value of each cell.

Sounds like a Yair Altman question.
