7 LAMBDA Helper Functions: MAP, SCAN, BYCOL, BYROW, REDUCE, ISOMITTED, MAKEARRAY. EMT 1749

Download Excel File: https://excelisfun.net/files/EMT1749.... Learn how to use the 7 helper functions for the LAMBDA function. Learn how to use LAMBDA to create a re-usable function, and then how to use LAMBDA as a function value in the LAMBDA helper functions: MAP, SCAN, BYCOL, BYROW, REDUCE, ISOMITTED, MAKEARRAY. Also see the Old School worksheet formula methods we used to use when we did not have these new functions. 1. (00:00) Introduction 2. (00:15) Function values are now in the Excel worksheet 3. (00:54) LAMBDA to make a reusable function. 4. (02:43) ISOMITTED Function to add message for missing arguments. 5. (03:39) How BYROW, BYCOL and MAP are related. 6. (04:32) How SCABN and REDUCE are related 7. (04:49) What is MAKEARRAY 8. (04:56) BYROW Function to create spilled row totals. 9. (06:56) BYCOL Function to create spilled column totals. 10. (07:41) MAP Function: three examples. 11. (08:53) How MAPS and BYROW are related. 12. (09:19) MAP function to spill results from the scalar AND Logical function. This MAP example uses a LAMBDA function that works across two columns. 13. (10:44) BYROWS to help calculate standard deviation of finance portfolio of stocks 14. (12:26) SCAN Function to create array of running total counts. This example uses SCAN to add and accumulate. 15. (13:27) REDUCE Function to add a set of numbers after they accumulate. 16. (14:10) SCAN Function multiply and accumulate. 17. (14:25) SCAN Function to join and accumulate. 18. (14:49) MAKEARRAY Function to create an array of random values. 19. (15:25) MAKEARRAY that uses row and column variable in LAMBDA. 20. (15:54) Summary and concluding video links
