(I'm assuming this question is for matlab/octave program.)
Answer: 55x1
Explaination: command testdata(deleteIndex) = [] will flatten matrix of (8x8) into a column vector of (64x1) and then delete values of 9 indexes(which are in deleteIndex).(i.e. 64-9 = 55). So, finally testData will be a column vector of (55x1).

The accounting for bonds payable is: not covered by IFRS the same except that market prices may be different because the present value calculations are different between IFRS and GAAP. o differs in that GAAP requires use of the straight-line method for amortization of bond premium and discount. essentially the same under IFRS and GAAP.

3. Eight Queens Write a program that places eight queens on a chessboard (8 x 8 board) such that no queen is "attacking" another. Queens in chess can move vertically, horizontally, or diagonally. How you solve this problem is entirely up to you. You may choose to write a recursive program or an iterative (i.e., non-recursive) program. You will not be penalized/rewarded for choosing one method or another. Do what is easiest for you. 3.1. Output Below...

1. Check Beer's Law by plotting absorbance vs molar concentration using 2. Is Beer's Law valid for this system? Explain your answer. 3. If Beer's Law is valid, the value of "E" should be constant. Use A-ECPL or E = A/(EL) and the data from Table II to calculate values of E for the five solutions below. The value of L is normally 1 cm so E - A/C in this experiment. Table...

Suppose you are given the following production function
Q= 21x + 9x2-x3
Compose a table calculating the Total Product (Q), Marginal
Product (MP) and Average Product (AP), for x ranging from 0 to 9
units.
Using the information from the table, graph these individual
curves and identify the rate of which diminishing marginal returns
are evident. Delineate the stages of production and
explain why Stages I and III are considered as
irrational whereas Stage II is termed as rational. What...
