I have three vector x which is 52x1 and y which is 21x1 and z which is 426x1 (lookup table axes) how can I interpolate for the point x_d,y_d,z_d? something like interp2 but 3D. If the lookup tables require different processing rules, then you can wrap two VLOOKUP functions inside of an IF function like so: =IF( test,VLOOKUP ( value, table1, col, match ),VLOOKUP ( value, table2, col, match )) This allows you to customize the inputs to each VLOOKUP as needed. ASCII table, character codes chart, hex/decimal/binary/HTML. Python supports a special "array" from the array module. Next, we have the far more popular Python list.
