Is there a way to apply multiple inputs to multiple functions?

I am looking for a way to generate a matrix of results from applying 4 different functions to 5 input values. For example:

• sin(x)
• cos(x)
• sqrt(x)
• round(x)

Using:

• x = 1.1
• x = 1.6
• x = 3.2
• x = 4.7
• x = 8.1

Is there any way to generate a 4x5 matrix with the results of each x-value applied to each function?

yeah, its very simple, if you go

 x = [1.1 1.6 3.2 4.7 8.1]

if you played around with it, then you'd figure out that if you stick x, as a matrix, in each of those functions you'll see that the function is applied to each value in x.

so we can then do something like this to concatenate it.

    result = [sin(x);cos(x);sqrt(x);round(x)];

where you'll then get a 4x5 matrix with the first row being sin and the last round.

since i've done 90% of the work there. i'll let you figure out how to write a function.
