[Solved] What is the issue with the following MATLAB code?numStr = '250'; val = int16(numStr); — Ans: int16 cannot convert strings directly; use str2double first | MATLAB

MATLAB - Cell Arrays and Structures

What is the issue with the following MATLAB code?

numStr = '250'; val = int16(numStr);

Aint16 does not support values above 127

Bint16 cannot convert strings directly; use str2double first

CThe variable name 'numStr' is invalid

Dint16 requires input to be a character array

Step-by-Step Solution

Solution:

Step 1: Understand int16 input requirements
The int16 function expects numeric input, not strings.
Step 2: Identify the error
Passing a string like '250' directly to int16 causes an error because it cannot convert strings to integers.
Step 3: Correct approach
First convert the string to a numeric type using str2double, then convert to int16: val = int16(str2double(numStr));
Final Answer:
int16 cannot convert strings directly; use str2double first -> Option B
Quick Check:
