# Simple MATLAB problem that has me stumped

• ja sam glup
In summary, the conversation discusses using an array to find values of y for the equation y = (e^3x) / (sqrt (x+1)) within the range of x = [1,10]. The attempt at a solution involved defining the function and using arrayfun(), but resulted in an error message. The solution involved using x = 1:10 and adding a dot to perform a value by value operation.

## Homework Statement

Use an array for single digit values of x [1,10] to find values of y for the equation y = (e^3x) / (sqrt (x+1)).

## The Attempt at a Solution

So, I tried defining the function as Function [ (e^3x) / (sqrt (x+1))] = y(x) , but that gave me an error message. I then tried to just define x and y first with syms x; and syms y;, and then define y as y = (e^3x) / (sqrt (x+1)).

However, since this is actually not a function, i was not able to arrayfun() to get the answer that I needed. This is my first MATLAB homework and the TA didn't explain anything, he just said to do it.

Any help would be greatly appreciated.

Here this will fix your problem

Code:
x = 1:10;
y= (exp(3*x)) ./ (sqrt (x+1))

Take note of the dot (" . ") That tells MATLAB to perform a value by value operation rather than a matrix operation.

## 1. What is MATLAB and how is it used in scientific research?

MATLAB is a programming language and numerical computing environment commonly used in scientific research. It allows for efficient data analysis, visualization, and modeling through its built-in functions and toolboxes.
