To allow the MATLAB parser to perform stricter checks on your code and avoid untrapped errors and other unexpected behaviors, do not include output arguments in the input to the eval function. For example, the statement eval(['output = ',expression]) is not recommended. Instead, specify output arguments to the eval function to store the results of the …When you execute find with a relational operation like X>1, it is important to remember that the result of the relational operation is a logical matrix of ones and zeros. For example, the command [row,col,v] = find (X>1) returns a column vector of logical 1 ( true ) values for v.This module explores some basic 3D point cloud processing techniques using MATLAB tools and segmentation.

Some problems require information about the locations of the array elements that meet a condition rather than their actual values. In this example, you can use the find function to locate all of the elements in A less than 9. I = find (A < 9) I = 8×1 3 6 7 11 14 16 17 22.If you’ve been browsing online classifieds or social media platforms, you may have come across ads for “$100 teacup dogs for sale.” The idea of owning a tiny, adorable dog at such an affordable price can be tempting.This set of MATLAB Multiple Choice Questions & Answers (MCQs) focuses on “Vectors and Matrices – 1”. 1. Vectors depend upon brackets while scalars don’t. a) True b) False View Answer. Answer: a Explanation: To declare a scalar, we only need to declare a variable in MATLAB with a constant expression.s = struct (field,value) creates a structure array with the specified field and value. The value input argument can be any data type, such as a numeric, logical, character, or cell array. If value is not a cell array, or if value is a scalar cell array, then s is a scalar structure. For instance, s = struct ('a', [1 2 3]) creates a 1-by-1 ...TF = matches (str,pat) returns 1 ( true) if the specified pattern matches str, and returns 0 ( false ) otherwise. If str is an array, then TF is an array of the same size. If pat is an array containing multiple patterns, then matches returns 1 if it finds that any element of pat matches str. TF = matches (str,pat,IgnoreCase=true) ignores case ...
