What is a vector in MATLAB?

• A vector in MATLAB is a two-dimensional array.
• A vector in MATLAB is a string data type.
• A vector in MATLAB is a mathematical function.
• A vector in MATLAB is a one-dimensional array.

What are the two types of vectors that MATLAB allows creating?

• Horizontal vectors and vertical vectors
• Row vectors and column vectors
• Scalar vectors and matrix vectors
• Single vectors and multiple vectors

What is the syntax for creating a row vector in MATLAB?

• Use curly braces with elements separated by spaces or commas.
• Use parentheses with elements separated by spaces or commas.
• Use angle brackets with elements separated by spaces or commas.
• Use square brackets with elements separated by spaces or commas.

What is a matrix in MATLAB?

• A matrix in MATLAB is a collection of strings
• A matrix in MATLAB is a one-dimensional array
• A matrix in MATLAB is a graphical representation of data
• A matrix in MATLAB is a two-dimensional array of numbers.

How can matrices be created with zeros and ones in MATLAB?

• Combine the zeros() and ones() functions to create a matrix of zeros and ones
• Use the twos() function to create a matrix of twos
• Use the zeros() function to create a matrix of zeros and the ones() function to create a matrix of ones in MATLAB.
• Manually input each element of the matrix using a loop

How can values be accessed from a matrix in MATLAB?

• By using the 'print' function
• By accessing the values directly without specifying indices
• By multiplying the matrix by a scalar
• By specifying the row and column indices within parentheses after the matrix variable name.

How can any row or column be deleted from a matrix in MATLAB?

• A(1,:) = 0; to delete a row and A(:,1) = 0; to delete a column

• A(2,:) = []; to delete a column and A(:,2) = []; to delete a row
• A(:,1) = []; to delete a row and A(1,:) = []; to delete a column
• A(2,:) = []; to delete a row and A(:,2) = []; to delete a column

What is the syntax to convert all letters in a string to lowercase characters in MATLAB?

• lower('YOUR_STRING_HERE')
• lowercase('YOUR_STRING_HERE')
• toLower('YOUR_STRING_HERE')
• convertToLower('YOUR_STRING_HERE')

How do you assign a value to a cell array in MATLAB?

• cellArray[2][3] = 'value';
• cellArray(2,3) = 'value';
• cellArray{2,3} = 'value';
• cellArray(2)(3) = 'value';

What is the syntax to access content of cells in a cell array in MATLAB?

• myCellArray(2)
• myCellArray{2}
• myCellArray[2]
• myCellArray(2,1)
