When multiplying two arrays in Matlab using the rules of linear algebra the number of columns in the first array must equal the number of rows in the second array the number of rows in the first array must equal the number of columns in the second array you need a period in front of the multiplication sign the arrays must have the exact same size and shape When combining two arrays in Matlab using the command A*B both arrays must be square the arrays must have the exact same size and shape the result is usually not the same as B*A all of the above When multiplying two vectors using the command A*B if A is a row vector then B must be a column vector A and B must both be row vectors A and B must both be column vectors please help with these multiple choice question

What does 'super()' do and give an example of why you would use it (you can answer directly or use pseudocode or a program to explain)?

In a letter to the editor of CACM, Rubin (1987) uses the following code segment as evidence that the readability of some code with gotos is better than the equivalent code without gotos. This code finds the first row of an n by n integer matrix named x that has nothing but zero values. for \( (i=1 ; i<=n ; i++)\{ \) for \( (j=1 ; j<=n ; j++) \) if \( (x[i][j] !=0) \) goto reject; println (First all-zero row Show Transcribed Text Rewrite this code without gotos either in C or Java. Compare the readability of your code to that of the example code. No hand written solution and no image
