I used A= readmatrix() to create a very large matrix from data in an excel file and now have:
[x1 z1
x2 z2
x3 z3 ] etc.
I'd like to take all the current "x" values in column 1 and apply the funtion y=ln(1+x) and create a new matrix with:
[y1 z1
y2 z2
y3 z3] etc.
I tried using a for loop, but didn't know how to input the existing x values into the function.
Any advice welcome, please let me know if you'd like more info.
