# Array Indices Must Be Positive Integers Or Logical Values

Array Indices Must Be Positive Integers Or Logical Values. The solution to the problem is to make sure that you'. Subscript indices must either be real positive integers or logicals.

Most arithmetic operations remove the logicalness from an array. Quite new to Matlab and i'm trying to get a code that basically checks the value of one array, compares it to each different value from a different array, and then if the number is bigger or smaller, either A is displayed or B. Until bright red text shows up informing you that the array index must be positive.

## I am using the mlabwrap module in python for my thesis and I have encountered an error : some times when I call my matlab function from my python code it stops and shows this error " mlabrap.error: Subscript indices must be either real positive integers or logicals" and the line where this error.

Warning: Integer operands are required for colon operator when used as index Warning: Integer operands are required for colon operator when used as index ??? The error is as follows: Array indices must be positive integers or logical values. This index specifies the position of each character of the string.

### Actually this error occurs because you attempted to use a non positive integer in the array.

The most common reason this message This error message can also arise if you use a noninteger (or negative) value to index. Can anybody tell me why the issue is here? Problem : The below error occurs quite frequently to me: "Subscript indices must either be real positive integers or logical" I want to have a general solution for dealing with above.

Problem : The below error occurs quite frequently to me: "Subscript indices must either be real positive integers or logical" I want to have a general solution for dealing with above. Both indices and logical values must be positive integers. Viewing a memory cell as an integer without being concerned about the details of the representation.

### The most common reason this message This error message can also arise if you use a noninteger (or negative) value to index.

Until bright red text shows up informing you that the array index must be positive. Most arithmetic operations remove the logicalness from an array. A(B), where B is a logical array, returns the values of A at the indices where the real part of B is nonzero.

Most arithmetic operations remove the logicalness from an array. Can anybody tell me why the issue is here? Why Am I Receiving Error Message "array Indices Must Be Positive Integers Or Logical Values".

The latter being an expression is parsed differently and so has. Can anybody tell me why the issue is here? Learn how to fix the Matlab error: Subscript indices must either be real positive integers or logicals.
