Convert Matrix to List?

[#1]

Hi JMP folks,

I can do this in a loop, but is there a simple one-liner to convert a one-dimensional matrix to a list? Something like:

cell_list = getmatrixaslist(cell_matrix);

Additional bonus question: is there an equivalent to the list LOC function for a matrix? I need to locate all rows in a matrix with a certain value. The LOC function does this for lists, but for matrices it finds all elements equal to 0.

Thanks!
Peter

You can use the LOC function to locate all rows of a matrix that are equal to a value. Consider the following example:

If my matrix is

m=[1,3,3,6,7,1,3,9]

then use the following to locate all rows of that matrix that are equal to 3:

loc(m==3)

This returns the following result

[2,3,7]

which is a matrix of row numbers of m that are equal to 3.

If you leave off the loc function and just use m==3, then you get a matrix of 1's and 0's, with a 1 indicating the value is equal to 3.

Here's the syntax for converting a 1D matrix to a list:

cell_list = as list (cell_matrix);

Thank you very much for your responses. It's easy when you know how!
