I am a beginner and this is a naive question.
I have the following data set.
row column height
1 2 96
3 7 67
9 25 77
......
I have a matrix of 50*100 data points and about 60% of them are zeros.
I want to put the height data into the matrix according to their row and column
numbers. does anybody have experience in setting up such matrix?
Your help is highly appreciated.
