Given two Year + 1/3/5 integers, generate a vector of all Year + 1/3/5 integers between them (inclusive)

array multiplication works if the two operands
after this command: v = 111:-11:1; how many elements will v have?
matlab

My start on an example:

yr_min <- 20181
yr_max <- 20195

as.numeric(paste0(rep(
seq(as.numeric(substr(yr_min, 1, 4)),
as.numeric(substr(yr_max, 1, 4))),
each = 3),
c(1, 3, 5)))

[1] 20181 20183 20185 20191 20193 20195

What is wrong with the above code? It will not generalize beyond situations where yr_min ends in a 1 and yr_max ends in a 5.

For example:

yr_min <- 20183
yr_max <- 20193

as.numeric(paste0(rep(
seq(as.numeric(substr(yr_min, 1, 4)),
as.numeric(substr(yr_max, 1, 4))),
each = 3),
c(1, 3, 5)))

[1] 20181 20183 20185 20191 20193 20195

The desired output is

[1] 20183 20185 20191 20193

Matlab: A Practical Introduction to Programming and Problem Solving, Both of these create a row vector variable that has four elements; each value is stored For example, 1:5 results in all of the integers from 1 to 5 inclusive: >> vec = 1:5 vec = 1 2 3 4 5 Note For example, to create a vector with all integers from 1 to 9 in steps of 2: >> nv = 1:2:9 the result would be 1 3 5 QUICK QUESTION! Write a script.Create a vector of five random integers, each in the range from -10 to 10.Perform each of the following:•Subtract 3 from each element•Count how many are positive•Get the minimum

I would recommend using bona fide dates in your calculation. This allows us to take advantage of base R's seq function:

x <- seq(as.Date("2018/3/1"), as.Date("2019/3/1"), by="month")
x[format(x, "%m") %in% c("01", "03", "05")]

[1] "2018-03-01" "2018-05-01" "2019-01-01" "2019-03-01"

If you really want the exact format you have, you can easily do that with another call to format:

y <- x[format(x, "%m") %in% c("01", "03", "05")]
format(y, "%Y%m")

[1] "201803" "201805" "201901" "201903"

Or, for your exact output:

sub("(?<=\\d{4}).", "", format(y, "%Y%m"), perl=TRUE)

[1] "20183" "20185" "20191" "20193"

Programming with Sets: An Introduction to SETL, To describe the set of all integers lying in the range M to N inclusive, where M and N are Sets of integers of the form {1,3,5,7,9} or {10, 5,0, -5,-10, –15) that is to say, sets that These notations will be used frequently in what follows. appear: {4,5,6,7,1,2,8,3,9,10} (or some other permutation of the integers from 1 to 10). Write a function called int_col that has one input argument, a positive integer n that is greater than 1, and one output argument v that is a column vector of length n containing all the positive integers smaller than or equal to n, arranged in such a way that no element of the vector equals its own index.

predefined data:

end_vec <- c(1, 3, 5)
yr_min  <- 20183
yr_max  <- 20193

code:

ans<-
c(
sapply(c(yr_min, yr_max), function(x) {n<-nchar(x);as.numeric(paste0(substr(x,1,n-1),end_vec))})
)

ans[dplyr::between(ans, yr_min, yr_max)]

result:

# [1] 20183 20185 20191 20193

Make the vector [1 2 3 4 5 6 7 8 9 10] - MATLAB Cody, More from this Author95 · Find state names that start with the letter N. 567 Solvers​. Pangrams! 2608 Solvers. Renaming a  I have a question about creating vectors. If I do a <- 1:10, "a" has the values 1,2,3,4,5,6,7,8,9,10. My question is how do you create a vector with specific intervals between its elements.

how can i solve this ,can anyone provide me with code? whats , If these three represent a valid date, return a logical true, otherwise false. If any of the inputs is not a positive integer scalar, return false as well. Note that every year that is exactly divisible by 4 is a leap year, except for years that are exactly if month==2 && day>28 (any(month == [1,3,5,7,8,10,12]) && day <= 31) || . Given starting and end points, write a Python program to print all odd numbers in that given range. Example: Input: start = 4, end = 15 Output: 5, 7, 9, 11, 13, 15 Input: start = 3, end = 11 Output: 3, 5, 7, 9, 11. Example #1: Print all odd numbers from given list using for loop

MATLAB tutorial, Greatly borrowed from MIT's MATLAB on Athena tutorial Creating and Working with Matrices If called with a matrix as its argument, max returns a row vector in which each element is All of these work for two scalars, including complex scalars. MATLAB has several operators that round fractional numbers to integers. Given two vectors A⃗ =4.00i^+7.00j^ and B⃗ =5.00i^−2.00j^ , find the vector product A⃗ ×B⃗ (expressed in unit vectors). Express your answer in terms of the unit vectors i^, j^, and k^. Use the 'unit vector' button to denote unit vectors in your answer. Express your answer using three significant figures.
